Set Screws

About Set Screws

Set screws (also sometimes called set pins, set bolts or grub screws) are important components in mechanical assemblies, securing one part to another without the need for a nut. Instead, the friction between the point of the set screw and the component holds it in place. Set screws don't typically protrude from the component being fastened because the entire screw fits into the threaded hole; this allows for a concealed fit.

Unlike standard screws and bolts, set screws are screwed into a pre-tapped hole. They come in a range of designs, like cup point, flat point and cone point set screws, each offering advantages for specific use cases. Because these screws are typically used within mechanical assemblies, they are usually made from strong materials like steel, stainless steel, or alloy steel, in order to be durable and reliable in different working conditions.
