# ANSI/ASME, DIN, JIS

Hex Socket Set Screw is a headless screw with a fully threaded body of uniform diameter and an internal hex socket drive, tightened using an Allen key.

It is also commonly known as a grub screw, hollow set, or HS. This type of screw is designed to press its tip against the surface of a component and is mainly used for positioning, locking, or securing mechanical parts.

The Cup Point type features a concave, cup-shaped tip. It is the most commonly used point style among hex socket set screws, providing strong holding power by slightly penetrating the mating surface when tightened.
