Parts of Screw: Manufacturing & Uses of Screw

Screws are likely the considerably majorly used stainless steel fasteners that are employed in each industry and factory.

The three basic parts of a screw are the head, threaded shank, and point.

They are critical to all work and equipment. In no way related to bolts, they are employed to confirm a minimum of two or more surfaces together.

As the screw moves through the surfaces, it “digs” out material by pars of its external threading. Regardless of whether you’ve employed screws, however, you might be new to their various parts.

Screws are in numerous cases self-threading (otherwise called self-tapping), while the screw is turned, the threads are shortened into the material, creating an inner thread that allows fully fastened materials together and forestalls pullout.

There are multiple screws for various materials;

Materials regularly associated with screws incorporate wood, sheet metal, and plastic.





  1. Parts of Screw  

The parts of the screw are mentioned below:

a. Drive

These parts are also called screw heads. The tip of the screwdriver which will adjust to rotate or pivot the screw in a certain slot is called a drive.

There are various sizes and states of drives available. As per that, it ought to be more acceptable to have different screwdriver tips in a personal toolbox.


b. Tip

The sharp or pointed edge of a screw is called a Tip. Many screws contain a sharp and pointed tip that is prepared to dig a hole into surfaces. The tip is usually thinner than the rest of the screw.

This allows it to pierce or enter in any case hard materials. Without a tip or with a wide tip a screw might oppose to pierce rigid materials. The tip often varies depending on what material the screw is planned to be used on.


c. Head

The head is the top part of a screw. There are two types of screw heads:

a. Traditional

b. Counter-sunk

Counter-sunk heads are planned or wished to rest flush with the surface into which they are pushed.

If we compare counter-sunk heads with traditional or conventional screws, conventional screw heads project away from the surface into which they are driven. Both traditional and counter-sunk screw heads feature at least one notches, which is developed to assist the utilization of a screwdriver.

You should push the screwdriver into these notches to force a screw into the surface, after which you can rotate the screwdriver.


d. Threading

The area or part of a screw that possesses helical ridges is called threading. Screws depend on this threading to remove material from the surfaces into which they are pushed. The threading primarily or fundamentally digs out material as the screw is pushed into a surface.

At the point when a screw is driven into a surface, it will displace a portion of the surface’s material. The material will travel up and out of the surface once it enters the helical ridges.

e. Crest

The crest of the thread is the important part of the thread, whether it is internal or external. The valley of the thread is called the crest.


f. Shank

Screws alike contain a shank. For wood screws, the shank is the unthreaded piece or part that is seen over the threaded part. Wood screws keep an unthreaded shank to make a more grounded and secure hold.

With the simple aspect of a wood screw being threaded, it presents a more stronger or grounded hold than that of conventional or standard screws totally threaded from forming to end.

Various sorts of screws have a fully threaded shank, signifying the threading develops as far as possible from the head to the tip. Wood screws are diverse in light of the fact that they quite usually have an unthreaded shank.


g. Thickness

The thickness of the screw is calculated or evaluated as well as set by two diameters which is the minor and major diameter.

The thickest part of the thread is called a major diameter and the distance across the base of the screw is known as minor thickness.





  2. Manufacturing Process of a Screw  

There are three important stages in preparing a screw that is as follows:

a. Heading

b. String rolling

c. Covering


The screw is prepared by utilizing wire. Afterward, the wire is trimmed to the proper length for the sort of screw being produced.

The head of the screw is prepared by the heading. The die’s shape in the machine provides the features to press into the screw head.

for example, a round head screw employs a round die.

The threads are made by pars of thread rolling. Be that as it may, some are a machine. At last, layering or coatings are done.

For example, electroplating with zinc or black oxide is applied to forestall corrosion.

  3. Uses of Screw  

The uses of screws are as follows:

a. Used in fitting the object in the wall.

b. Used in preparing or fixing machines or electrical devices.


This was for the parts of screw.
