What is a set screw and why is it needed?

The set screw is a special type of fastener that is used for reliable fixation of parts in mechanisms and technical devices. Thanks to its special design, it ensures a tight fit of parts and prevents them from shifting under load. The main task of set screws is to secure moving elements such as shafts, gears, bushings and other components that require precise positioning. Guzhons, as they are also called, are actively used in mechanical engineering, electrical engineering, the furniture industry and other areas. They help to connect different structures without using nuts or additional fixing elements, which makes them indispensable in many technological processes.

Features of the design of the set screws

Installation screws have several important design features that determine their effectiveness in installation work. The main characteristic is the thread, which can be metric or inch, depending on the standard of production. This ensures compatibility with a wide range of parts and mechanisms. Set screw sizes range from small models for precision machinery to massive options for industrial applications. The materials from which such screws are made usually include high-strength steel, stainless steel or brass, which increases their wear resistance and resistance to corrosion. Additional strength and durability are provided by special coatings such as galvanizing or oxidation. Also, the design can include an internal hexagon or other types of grooves for convenient installation with the help of appropriate tools. That is why it is worth buying set screws to solve certain technical problems. 

Types of installation screws

There are several basic set screw standards on the market, each of which has its own characteristics.

FROM 913 – screws with an internal hexagonal hole, which provide reliable fastening and are suitable for high-precision mechanisms.

FROM 914 – models with a pointed end, which provide better fixation in the holes and reduce the risk of accidental unwinding.

FROM 915 – installation screws with a countersunk head, used in cases where the smoothness of the surface after installation is important.

Application of installation screws

Set screws are widely used in various industries. In mechanical engineering, they provide reliable fastening of moving parts such as axles and gears. In electrical engineering, they are used for connecting current-conducting components, and in the furniture industry - for hidden assembly of parts. Also, such screws are used in construction for the installation of various structures, in particular carts, fasteners and support mechanisms. Due to their versatility, they are indispensable in the production of machinery and industrial equipment.
