Screwdriver Manufacturing Process
The Complete Guide Screwdriver Manufacturing Process
Our guide explains everything you need to know about screwdriver Manufacturing Process and the different types available.
1.The first stage is to get enormous coils of green wire in diameter. This wire is then treated in a manufacturing facility, where it is pulled to the precise diameter required for screwdriver manufacture. This is accomplished with an adjustable machine that gradually decreases the wire’s diameter to the appropriate size.
2.After drawing, the wire is annealed (heat treated) to acquire the necessary tensile strength of the metal.
3.The wire is then straightened using a string forge before being moved to a cold forming press, where it is cut to the necessary length and formed into the screwdriver tip and “wings” that will fit into the handle. These wings may be viewed through a clear or semi-transparent plastic grip. The freshly produced “bar” (the real screwdriver minus the Ats handle) is then heat treated in an in-line furnace at around 1,555 degrees Fahrenheit (846 degrees Celsius). This is a continuous flow operation, and when the bars exit the furnace, they fall into an oil quench to cool. The bars are then placed in a draw back oven (450 to 500 degrees Fahrenheit or 232 to 259 degrees Celsius) and cooked to the desired hardness.
4.Before assembly, consumer model screwdrivers are nickel-plated, or coated with a protective layer of nickel. If the screwdriver is intended for professional usage, it is taken to a hand-grinding section, where the tip is ground to size. The shank is chemically machined, then polished. The screwdriver is then immersed in a nickel flash bath and electrically chrome coated.
5.After the cold forming press (step #3 above) cuts the wire, the screwdriver is delivered to a “swage and grind” process, in which dies make blades for the tip out of the heated wire. The tool is then ground to make the wings.
6.If a professional model is being manufactured, the bar is routed to a tipping operation (an automated tipping machine that forms the bullet point) and then to a profilator machine (which cuts a “profile”). The latter machine creates four grooves or slots on the sides above the tip. The wire is then winged and heat-treated in the same manner as the flat-tip screwdriver bars. Consumer Phillips screwdrivers are nickel-plated, but professional models are polished and nickel/chrome plated.
7.A screwdriver’s handles are typically constructed of cellulose acetate; it is brought to the manufacturer in powder form (cellulose acetate rosin) and then blended with a liquid plasticizer in a massive mixer that contains around 1,000 pounds (454 kilograms) of the combined material. If you want a colorful handle, add pigments to the blender. The resultant paste, which has the consistency of thick cake batter, is then fed into an extruder (a machine that forces material out via an orifice, similar to how a meat grinder forces out strings of flesh), which produces a solid piece of cellulose acetate. The cellulose acetate is then separated into tiny pellets.
8.The pellets are then fed into another extruder, which extrudes the components for the handles into bars ranging from 8 to 10 feet (2.4 to The slotted screwdriver is the oldest and most popular form of screwdriver, fitting screws with a single slot in the head. There are over thirty distinct types of screwdrivers available today in a variety of sizes, each with a unique purpose and intended to fit into certain screws.

Three meters in length. If a two-color handle is required, a second extruding machine can be connected to the first to produce a single, two-color rod. The rods are then fed into an automated turning machine, which forms and cuts the handles to the desired length. A hole is then made in the handle to insert the bar.
9.The handles are machine cleaned and dried to remove grease, oil, and extra scraps from the extruder and turning machine. The handles are then submerged in an acetone vapor solution to melt and smooth the exterior of the handle. Acetone vapor is very combustible, hence this procedure takes place in an explosion-proof chamber.
10.The manner of final assembly is determined by the quality of the tool being manufactured. Professional models are constructed separately on a horizontal assembly machine that uses hydraulics to drive the bar into the plastic handle. A hot stamp is used to mark the handles right before they are placed in the assembling process. Each machine must be assembled by one trained person.
Other types may be constructed using hydraulic presses three at a time. The cheapest versions are assembled six at a time on a single machine and then arranged by robot on a skin card machine, which packages the screwdrivers for bulk distribution.
11.Depending on the use, the screwdrivers may be equipped with a unique handle cover prior to shipping. A rubber cap put over a screwdriver handle, for example, might be more pleasant for a professional who uses his instrument for five or six hours every day. A broad handle with deep grooves may be great for some professionals, but a home handyman who assembles a lamp or cabinet every six months may not want or want to pay for the extra comfort.

Screwdriver Uses and Applications
The screwdriver is one of the most important hand tools in every toolkit. A screwdriver is essential for many situations and occupations that require releasing or tightening screws.
Some of the most popular applications of screwdrivers are:
- Electronics & Electrical Equipment
- Opening Mobile Phones
- Opening computers
Mechanical and - Industrial Production
- Woodworking and Carpentry
- Metalworking and attaching wood to metal
- Flammable surroundings.
It is also worth noting that some screwdrivers are better suited to certain situations. For example, the best electrician’s screwdrivers will be insulated to safeguard the operator. Phillips screwdrivers, on the other hand, have a wider range of applications due to their versatility.
Screwdriver Manufacturing Process FAQs
Screwdrivers are made from basic materials such as steel wire, plastic, nickel, and chromium. The screwdriver bar is made from steel wire, the grip is made of plastic, and the screwdriver’s steel tips are plated with nickel or chromium.
Drive tips can be made from a variety of metals and alloys, including:
- Titanium
- Stainless steel
- Tool grade steel or S2
- High-speed steel or HSS
- Chromium-vanadium-molybdenum or CVM tool steel
- Other non-sparking metals to reduce combustion risk
Insert the screwdriver tip into the screw head and spin the handle clockwise while exerting pressure to keep the tip securely in place. Continue to spin the screwdriver firmly, making sure the screw is straight as it enters the material.
