What is a Hex Head Screw?

A hex head screw, also known as a hexagonal head screw or cap screw, is a type of fastener characterized by its hexagonal head. This design allows for secure tightening and loosening using a wrench. The hexagonal shape distributes the applied force evenly, minimizing the risk of stripping or damaging the head. The versatility of hex head screws makes them suitable for a vast range of applications in various industries.
