Hex Set Screws & Grub Screws

A set screw is a hardened, threaded fastener designed to hold adjustable components on a shaft. Some set screw variations possess a hex head, while headless, sometimes called grub screws, are characterized by a hex or slot recess to allow for tightening and loosening. Set screws are an effective way to hold pulleys, gears, and other components on shaft while still allowing adjustment of the retained part.
