Socket Set Screw DIN913 Stainless Steel China Direct Factory

Socket set screw is a type of screw that is designed to be used in applications where a secure and tight fit is required. It has a headless, cylindrical shape and is threaded along its entire length. The screw is typically tightened using an Allen wrench or hex key, which is inserted into a small socket or indentation in the top of the screw.

Socket set screws are commonly used to secure one object to another, particularly in situations where traditional fasteners may not be suitable, such as in machinery, appliances, and electronics. They are also used in applications where a flush surface is desired, as the headless design allows the screw to sit flush with the surface it is securing.

The threads of a socket set screw are designed to grip the material into which it is being threaded, creating a secure and permanent connection. They can be made from a variety of materials, including stainless steel, brass, and alloy steel, and come in a range of sizes and thread types to accommodate different applications.


What is Socket Set Screw used for?

Socket set screws are often used to fasten gears, pulleys, and other rotating components to a shaft. They can also be used to secure knobs, handles, and other components to a threaded rod or shaft. In addition, socket set screws can be used in conjunction with a threaded insert to create a strong, permanent connection between two components.

Because socket set screws are headless, they can be used in applications where a traditional screw head would interfere with the operation of the machinery or equipment. Socket set screws are available in a variety of materials and sizes, making them suitable for a wide range of applications.
