CUP POINT SOCKET SET SCREWS APPLICATIONCup point socket head cap screws feature a headless design with a concave (cup-shaped) end and are driven by an internal hex socket. Unlike headed screws, they are flush with or embedded in the workpiece surface, with the cup-shaped tip forming a tight, non-slip hold by pressing into the mating component. This makes them good for applications such as securing pulleys to shafts, locking mechanical gears, fastening tool handles, and stabilizing components in industrial equipment.ABOUT THIS CUP POINT SCREWSThis screw is manufactured from high-strength carbon steel with a black oxide finish. The carbon steel base delivers robust tensile strength for secure fastening, while the black oxide coating forms a protective layer that enhances wear resistance and provides moderate corrosion protection.
