What is a set screw?

A set screw is a type of screw that is typically used to secure an object within or against another object. It has a headless design, meaning it does not have a protruding head like other types of screws. Instead, a set screw has a flat or slightly rounded top that is usually hexagonal in shape.

Set screws are often used to secure components such as gears, pulleys, or shafts in place. They are commonly found in machinery, equipment, and furniture. Set screws are designed to be tightened into a threaded hole or set into a groove on a shaft, providing a strong hold and preventing the object from moving or rotating.

One of the key features of set screws is their ability to exert pressure without the need for a protruding head. This makes them ideal for use in applications where a flush surface is desired or where space is limited. Set screws are available in various materials, including steel, stainless steel, and brass, as well as in different sizes and types of threads.

When using set screws, it is important to ensure that they are properly tightened using the correct tools to prevent stripping or damage to the screw or the object it is securing. Additionally, periodic inspection and maintenance of set screws is recommended to ensure they remain secure and in good working condition.
