  • Product Description
Overview
Set Screws are usually headless but are sometimes headed fasteners with external machine screw threads and a point that is application specific. Despite being heralded early on as "an invention of the devil," they are the de facto method used to locate and fasten collars, drive wheels, gears, knobs, pulleys and other parts to shafts. Aside from their popularity in collar-type applications where headless set screws are fully recessed, they can also fasten components together. When tightened against a shaft—or when their tip mates with a hole in the shaft—they prevent rotational (torsional) and lateral (axial) movement and resist dynamic loads like vibration. For better point contact and to prevent a burr from interfering with part removal, the shaft may have a milled flat. Unlike socket Head Cap Screws, which create clamping force by tension, set screws are considered a compression fastener because they hold parts in place using point penetration and friction as a result of the clamping action. When their point is spotted, shear comes into play. Set screws are also known as:  Allen screws, grub screws, hexagon socket set screws.
