Self-tapping screw production technology
Technological processes in the production of self-tapping screws begin with the selection of suitable steel; it can be carbon, brass, or stainless. Raw materials are purchased at specialized metal rolling plants, in the form of a rod or wire. The production of self-tapping screws is similar to the production of nails, but the process differs in some nuances and equipment requirements. The production of self-tapping screws requires specially prepared equipment and occurs in stages:
- A blank is created from metal wire of the required diameter. The length of the workpiece must correspond to the finished product; cold heading equipment is used to make the cap.
- Before applying the thread, the self-tapping screw blanks enter a hopper, where they are prepared for transfer to the machine on which the thread is applied.
- The parameters of strength and endurance of self-tapping screws, in accordance with the declared indicators, are achieved by hardening in an oven. The temperature reaches over 900 degrees, then the metal tension is released in a furnace at a lower temperature.
- The anti-corrosion properties of an almost finished product are achieved by immersing them in special baths, the galvanic coating is applied in stages, and at the end it is treated with an electrolyte from zinc anodes to consolidate the result.
When producing screws, a machine called a centrifuge is used for drying, after which you can see the finished product. The size of production affects only the throughput of the machines and machines used; control over the quality of products and the production process can be carried out by one person.
Chinese and domestic machines
Russian manufacturers are trying not to be inferior to their Chinese colleagues in the development of this equipment.
You will find interesting offers at Kupra PJSC, Avto LLC, Monolit CJSC, Technoservice Krasnaya Zarya LLC and SAMSTAL LLC. Chinese devices - Candid and INNOR have also managed to prove themselves to our customers.
For example, for novice businessmen, you can offer a budget Chinese model; it can even fit in a garage. The work process is semi-automatic, so you will have to hire an operator. The number of products made per minute is only 25. But this machine also has advantages:
- cost about $3000;
- The settings provide for the production of various products: self-tapping screws, screws, bolts.
However, prices for Chinese, fully automatic, cold heading and thread rolling machines can reach up to $150,000.
So before you start a manufacturing business, do your market research thoroughly. Identify items that are in demand and think about how you want to organize the processes for manufacturing self-tapping screws. The need to purchase equipment of limited specialization or organize a full-fledged production line will depend on this.
The construction market is now on the rise, but even in times of economic crisis, the demand for such products will remain, because repair work is carried out regardless of the economic situations occurring in the country. We recommend looking at existing manufacturers of self-tapping screws and conducting competitive intelligence.

Where to begin?
Carefully drawing up a well-thought-out business plan guarantees 50% of the success of your business. But, before you start planning, do not forget to go to the Federal Tax Service branch of your city and register an individual entrepreneur. This procedure does not take much time, and the amount of the state fee for registration is purely symbolic - 800 rubles. Armed with a pen and paper, first think through and answer the following questions in as much detail as possible:
- Where to rent a room?
- Which manufacturers should you buy raw materials from?
- Which equipment is better to purchase (new or used)?
- What will be the number of items in the product range?
- Where to find conscientious employees?
- Who should sell the products to?
Having answered (at least partially) these questions, you can safely proceed to the next stage of implementing this business idea - finding a suitable premises.
Renting a production workshop with an area of 500 to 700 square meters is not an easy task. You should look for premises either outside the city limits or at the maximum distance from residential areas - noise pollution from working machines will be quite significant. The workshop must fully comply with sanitary and fire safety standards and be connected to a stable electrical network.
The average price in the Central Federal District for renting such premises is approximately 100 thousand rubles. Monthly utility costs will fluctuate around 15 thousand rubles. Solving the next issue regarding the purchase of raw materials and equipment will require even more significant nervous and financial costs.
Necessary equipment
The price of production equipment for self-tapping screws is high, so it is necessary to carefully study the design and performance. There are many models on the market, the price range varies depending on the purpose, country of manufacture, and production speed. The most common installation is a line for the production of self-tapping screws, where metal is harvested, threads are applied and heads are made, drying and galvanic processing are carried out.
Self-tapping screw production line
The productivity of the machines is selected in accordance with the needs of production
There are various automatic models that produce from 30 to 300 screws per minute; it is important to understand that the price of the device depends on this indicator. Control over product quality and technical condition of equipment is carried out by trained operators
The number of people in production depends on the volume of the line and the work plan.
Drawing machine
Procures rods at the initial stage of the process. Production begins with a furnace with spinneret holes through which the wire passes and is reduced in diameter. Drum-type raw materials are used for the process, as they are easy to install into seats. For prolonged use and compliance with temperature conditions, the equipment is cooled with a cutting fluid.
Cold heading equipment
The main work of a cold heading machine for self-tapping screws is the production of caps and special holes on them for working with the tool. Before processing, the raw materials are divided into an even number of products, then the screw head is formed.
Cold heading machine
Cold heading equipment requires adjustment and technical maintenance. Correct alignment of all systems will allow you to achieve a high-quality self-tapping screw at the exit, convenient for the client to work with. The equipment controls the supply of raw materials automatically, then, after work, dumps it into a hopper or basket.
Thread rolling machine
The equipment is equipped with a small conveyor with fastening elements. Next, the workpiece is processed with dies on both sides. The knurling elements are adjusted according to the available stroke; this happens when the type of part is changed. The pitch, shape and number of turns on the product completely depend on the element used and the correct setting. Each different type requires a separate removable tool.
Hardening equipment
After the above processes, the product appears finished, but is not usable. Machines for the production of self-tapping screws are not capable of working with solid products, so hardening occurs at the end of the process. The hardening furnace is set at a temperature of about 900 degrees, after the process the products are placed in a furnace with a low degree.
Tempering furnace
Due to the temperature difference, the metal relieves stress and is less prone to fractures. After hardening, washing is carried out to clean the finished product from traces of dirt and carbon deposits, and cooling also occurs.
Electroplating equipment
Galvanic coating is necessary for anti-corrosion properties and increased mechanical parameters of self-tapping screws. The process is carried out using several baths with different solutions, in which the part is processed sequentially. The initial stage is immersion in a bath with a degreaser, then a phosphate solution is applied, then oxide, etc. After all treatments, rinsing with water occurs, and a zinc coating is applied under electrical influence.
Drying and packaging machines
To dry the finished product, a drum with a centrifuge is used, the work is carried out on the principle of a washing machine. For packaging, bags with the possibility of packaging several dozen pieces are used. In wholesale trade, goods are packaged in boxes or other metal containers.
Assortment of self-tapping screws, manufacturing features
Self-tapping screws are available in a wide range, as a rule, it depends on the equipment used, it is expensive, so it is important to choose the shape, size and for what purposes they are used:
- Classic on metal. A common product, this self-tapping screw has a pointed end and frequent turns close to each other. Made from high-strength galvanized steel.
- Self-tapping screw for metal with a drill end. At the end of such a self-tapping screw there is a drill, which ensures a more confident entry into the metal, without pre-drilling.
- Self-tapping screw for wood. The difference between the previous ones is small: the distance between the metal turns is slightly larger.
- Furniture screw. It has a second name, confirmat, and is used for surfaces made of MDF and chipboard. This type of screw can have a variety of heads.
- The hex self-tapping screw is suitable for working with wood and some types of concrete, but it should be considered if you have wholesale outlets for distribution.
- Self-tapping screw for roofing - the head and diameter have different values, the washer is made separately.
Other subtypes of the product are not in great demand; you should focus on them only if you have regular customers when expanding production.
In addition to self-tapping screws, you can also produce pellets - these are wooden granules that are used in many areas of life. We also have a business plan for the production of liquid stone.
Features and Service
AG4116 can be called one of the most popular conveyors. The work uses steel wire, the diameter of which is 0.8–8.0 mm. It is sold in reels from 5 to 1000 kg. This version weighs about a ton, has dimensions of 195x116x106 cm, and is equipped with an asynchronous three-phase motor with a squirrel cage rotor (4A112M4U3). The productivity of the device reaches up to 500 units. products per minute. You can also use galvanized metal threads on this installation. It is noticeably different in strength and elasticity.
Azov cars also have excellent performance:
- length, width and height of the structure – 150x190x110 cm;
- weight – 2900 kg;
- electric motor – 5.5 kW;
- volumes per minute – 525 pcs.
This nail production machine produces construction hardware with a circumference thickness of 0.5 cm and a length of up to 15 cm. A distinctive feature of this mechanism is the adjustment of the longitudinal size of the rod. For its full operation, like most conveyors, a voltage of 380 V is required.
Some prototypes of this technology vibrate strongly when turned on.
Therefore, it is important to install it correctly on the floor
An easier approach is to use washers that dampen vibration. If this is not done, constant vibration will lead to loosening of the bolts, and the nailing machine will eventually become unusable.
The servicing procedure also includes lubrication of the operating elements: there is a lubrication map on the panel, which indicates all the places for filling specialized oil. This must be done so that the moving parts of the device do not jam.

Advantages and disadvantages of nail pressing machine
Pressing machines have higher productivity, but require frequent replacement of dies and jaws. High loads on the forming elements of machine tools lead to their rapid wear.
Pressing machines are designed in a similar way, but instead of a hammer, they have a stamp that forms the head of the nail with gradual pressure. The stamp is driven by a figured washer or an eccentric. In the opposite direction, the wire is fed forcibly (unlike impact machines, where it occurs under the action of a spring). This design increases productivity by almost 2 times. In pressing machines, production waste constitutes about 3% of the weight of the wire used. These are “petals” and marriage.
Machines for producing self-tapping screws at home
The range of machines is quite wide. You can pick them up at an affordable price with little productivity. Or you can purchase equipment that will produce a large number of hardware per shift.
The cheapest equipment for the production of self-tapping screws
The most interesting machine for home business is the Candid model AS3016. This is a semi-automatic machine for the production of hardware, self-tapping screws, screws. Its price starts from $3000. But in this case you will have to sacrifice productivity, which is only 25 units. in a minute
Please note that the machine is semi-automatic, which means that some operations must be performed by the machine operator. But if you are new to this industry and are just starting to explore the market of screws and self-tapping screws, then you should consider purchasing a budget model such as the Hangzhou Candid AS3016
Equipment for industrial business retains its value very well. By investing in it, you preserve your capital for years - after all, it is an asset that brings money. Figuratively speaking, a machine for printing money. And when you have already established a sales market, you can cash out your assets and move on to more expensive machines with significantly higher productivity.
Chinese and domestic machines
In the production of screws and bolts, the process is divided into two main operations:
- Specialized cold heading machines form blanks with “heads” of various types
Automatic thread rolling machines roll threads onto workpieces at a speed of 60 pieces of hardware per minute.
Such equipment is produced in Ukraine, China and Taiwan. On the territory of the Russian Federation there are only a few manufacturers producing such equipment. Therefore, purchasing a machine is a rather expensive operation: you need to pay not only for the purchase itself, but also for delivery.
The market leaders in the production of machine tools are:
- LianTeng (Taiwan);
- FOB (Taiwan);
- Candid (China);
- INNOR (China);
- KUPRA (Ukraine: PJSC "Odessa plant for the production of forging and pressing machines");
- SAMSTAL (Russia, Samara: SAMSTAL LLC).
These machines differ in the productivity of products per minute. The simplest machines produce about 60 parts per minute, while others have the ability to produce up to 250 parts per minute. Some models can be customized to produce other products. This is a significant plus, since you can expand your product range over time, and there will be no need to spend money on purchasing specialized equipment.
The price of the most inexpensive models of automatic machines with a productivity of more than 50 pcs/min. starts from $13,000.
Summary
To summarize, I would like to note that, despite the apparent simplicity of this type of business, you may encounter a number of problems, ranging from finding qualified workers and raw materials to opportunities to sell your products.
If you cannot agree on sufficient sales of finished products, preferably on an advance payment basis, then you risk investing significantly more money than originally planned. After all, part of the finished product will be in the warehouse, and accordingly you will receive less profit.
The production equipment, although automatic, still requires little human intervention. If the equipment turns out to be of poor quality, then repairing it can be expensive, because production will stop during the repair.
If you are not a beginner and know how to make self-tapping screws, then you will be able to handle this type of business, such as the production of hardware. And with good communication skills, you can easily sell all products and increase production. So, this type of business is likely to be successful for a competent person with at least minimal knowledge of production.

The selection criteria listed are the main ones, therefore, before purchasing a machine, you should find out all its characteristics and correlate them with the requirements that will be placed on the equipment at the enterprise.
Conclusion
The main step on the path to opening your own business for the production of hardware is the choice of a high-quality machine that is suitable in terms of power. After purchase, you will need to properly install and connect it.
It will also be necessary to purchase auxiliary devices and tools, and of course, consumables, through the use of which it will be possible to obtain products of the highest quality.
What is a cold heading machine?
This equipment belongs to the group of machines:
- stationary mid-size;
- universal expressways;
- automated two-impact;
- continuous action.
Machines of this type can be used to produce not only self-tapping screws themselves, but also almost any other types of fasteners - bolts, screws, etc. In this case, everything depends on the settings of such equipment.
Cold heading machines are mounted on a rigid welded frame. The wire is fed to the main unit in them from the coil using a ratchet device step by step. The length of the workpiece in machines of this type is adjusted by moving the stop. Landing blows in the equipment are performed with a punch. The first blow drives the rod towards the stop, and the second blow forms the head.
It is therefore clear how self-tapping screws are made at enterprises. The technology for producing such fasteners is, in principle, not too complicated. At the same time, the cold heading machines themselves produce workpieces very quickly. Depending on performance and power indicators, one such unit can produce up to 100-300 screws per minute.

The best machines for the production of self-tapping screws
Domestic and foreign companies are engaged in the manufacture of machine tools. Models differ from each other in technical characteristics, which in turn affects the performance and price of the device.
The simplest machines produce about 60 parts per minute, and more advanced ones produce up to 250 pieces/min. Such moments can greatly influence the payback period of the equipment.
Some models can be configured to produce other products; in the future, this will help expand the product range without spending money on purchasing additional machines.
The market leaders in the production of machines for fasteners include:
- Taiwanese companies LianTeng and FOB;
- in China these are Candid and INNOR;
- representative of the Ukrainian market – KUPRA;
- Russian
It is economically profitable to buy equipment in the above countries; you can always combine a production line using machines from several manufacturers.
As for the cost, we need to proceed from the requests of entrepreneurs. If we are talking about a small enterprise and new equipment, then according to professionals, at the initial stage the purchase will cost at least 700,000 rubles.
On average, if we allow the purchase of machines from used to new and multifunctional options, then the range will be approximately from 300 thousand to 2 million rubles.
Financial side of the issue
Revenue part
To understand the full benefits of this activity, it is necessary to carry out several calculation measures.
- The number of products produced per day is 140 units. The cost of one piece is 20 kopecks.
- From this we can conclude that the daily revenue will be equal to 28,000 rubles, and the monthly figure will be 600,000 rubles.
- For a year of production and successful sale of products, you can count on receiving 7.5 million rubles.
Next, you need to calculate the amount of initial costs required to start the activity. They also consist of several areas that require special attention and approach.
Initial expenditure directions
Initial costs consist of several items, which include the following areas.
- Machines for self-tapping screws - 600,000 rubles per piece.
- Consumables, 20 tons - 50,000 rubles.
- Other types of raw materials – 50,000 rubles.
- Additional costs – 300,000 rubles.
In total, we can conclude that the start of production is possible if there is an amount of 1,000,000 rubles.
Diagram of a nailing machine with a description of the operating principle
Schematic representation of the percussion device.
Wire nails are produced using impact and pressing machines. The most common impact machines are those that shape a nail using two hammers.
The wire is passed between two rows of rollers a, a. Next, it enters the feeder A (formed by the pawl b and the spring c pressing it), which oscillates with an amplitude equal to the length of the nail with a margin for forming the head. To increase/decrease the amplitude, the crank pin e is used. The feeder is driven by the crank e, the rod d, and the lever system d.
Having passed the feeder, the wire is driven between the clamping jaws w, w', and w is static, w'- is affected by the pressing force of the lever z, moved by the figured washer k (figure 14).
The cheeks are equipped with serrated grooves that allow you to fix the wire when riveting the head. There is also a shape in the cheeks that matches the geometry of the bottom of the cap.
Behind the cheeks there are knives p, p', respectively moved by levers o, o', which move under the influence of washers c and c', on the outer surface of which shaped grooves are cut (figure 14).
The knives have a pyramidal shape (figure 16). Cutout a serves to press the sharp end, blades b cut off excess. The remaining “petals” are removed during polishing.
A design feature in which the knives barely touch each other allows you to avoid rapid dulling of the knives. This design does not allow the nail to be completely cut off. The final separation of the product from the wire occurs with the help of an ejector t, the movement of which is imparted by levers y and rod f, driven by cam x.
The spring n, n' strikes the protrusion of the hammer l, giving it an impulse. The hammer strikes the nail, forming the head. A wooden spring (in some cars a steel one) is compressed using a cam m (figure 15, curve D).
The graph (Figure 15) shows the order of individual working strokes of the machine for producing nails. The feeder, which feeds the wire forward, corresponds to curve A.
The moves of the cheeks holding the wire are described by curve B (when the feeder moves the wire in the opposite direction, the cheeks do not fix it).
The working stroke of the scissors from the moment the wire is fixed is described by curve G.
The work of the ejector separating the finished product is shown by curve B.
The sequence of hammer operation is visible on curve D.
Next, the feeder occupies the extreme operating point, the cheeks open, and the work cycle begins from the beginning (curve B).
The difference between nominal and actual performance is about 20-40%. The reason for this is downtime due to the replacement and installation of tools, filling machines with new circles of wire, defects, etc. When making nails, from 2.5% to 3.5% of the material is lost on the “petals”. Losses due to defects reach up to 1%.
Wire for the production of self-tapping screws
To make hardware in the form of self-tapping screws, wire made of high-carbon and stainless steel or brass is used.
Depending on the products being manufactured and production volumes, the entrepreneur can purchase raw materials in the form of blanks or wire of a certain diameter. There are many factories supplying these raw materials. You shouldn't have any problems finding suppliers
When choosing a supplier, you should pay attention to the price of raw materials, their quality and proximity to your workshop. The proximity of the supplier to you will help reduce delivery time as well as transportation costs
Market assessment
The construction market gives Russian entrepreneurs enormous scope for running their own business.
Even the crisis had almost no effect on the level of demand. Prices for many finished products have increased altogether. A competent approach to doing business will allow the entrepreneur, over time, not only to increase the quality and volume of production, but also to develop a client base that will constantly need self-tapping screws. And the wider this circle of customers is, the more opportunities for expansion the businessman will have.
On the Russian market, most of the self-tapping screws are manufactured by metal processing companies with large annual turnover. There are significantly fewer small producers, but they also have opportunities for further development. Of course, their products are not so well known to domestic buyers, since they are usually sold in regional markets, namely in hardware stores, shopping centers or construction warehouses.
A business in the production of self-tapping screws is also interesting because it can be opened even with minimal investment. It is not necessary to immediately equip a full-fledged workshop. There is an option for producing small batches. Even if you produce about 2,000,000 pieces of self-tapping screws per month, you can count on a good profit.
Application of hardware products
Self-tapping screws are used in different directions and areas. Production can be provided by more than one construction company or wholesale client. Main consumers of hardware products:
- Construction organizations, large and small teams.

Plant for the production of hardware products
The profitability indicators of the hardware business always remain at a high level. Opening production in a weakly competitive market will allow the equipment to be repaid in less than six months during the construction season. It is worth noting that the purchased equipment is not so subject to wear and tear, so the investment will bring profit for many years. Construction work will always exist in everyday life of mankind; repairs of various types of premises cannot be carried out without the appropriate materials.
Workshop employees
When hiring workers for your production, special attention should be paid to their qualifications. Despite the fact that wages for skilled workers are higher, you can still save a lot
A more qualified craftsman will be able to produce high-quality products in a shorter time. And this, in turn, will not only lead to cost reduction, but will also increase the prestige of your products due to improved quality.
The wages of workers can be either fixed or depend on the quantity of products produced. At the beginning of production, when the sales market has not yet been established, it is worth offering workers a fixed payment and small bonuses if the production plan is fulfilled. Then, when you already have established sales channels, you can transfer your employees to piecework-bonus wages, which will encourage them to produce more products with high quality.

Having registered your enterprise and decided on the production capacity, you need to select premises and calculate the initial investment.
The calculation of the initial investment directly depends on:

These are quite suitable conditions for this business idea.
For the production of screws at home, a garage with an area of at least 18 m2 is suitable. It must be equipped with a good ventilation and heating system. The production area must be well organized, and the general environment must comply with all labor safety regulations.
Choosing the optimal tax regime
In the all-Russian classifier of economic activities, the business of producing self-tapping screws has code 25.94 OKVED 2. This means that you can work and pay part of the money you earn to the budget under a simplified taxation system. In this case, you can deduct 6% of the total turnover or 15% of the difference between gross income and expenses to the state treasury. In the latter case, you must have all the documents confirming the company's expenses.
For entrepreneurs who plan to organize the operation of a large plant, focusing not only on the domestic market, but also on buyers abroad, it is best to work under the general taxation regime. To do this, you will have to hire 1-2 accountants, but for a serious enterprise, this is quite normal practice.
