A DIN 933 hex head set screw is a fully threaded, high-tensile metric fastener with an external hexagonal head, primarily used for strong, structural connections in machinery and construction. This standard (now largely superseded by ISO 4017) is referred to as a "set screw", but its function is a general-purpose structural bolt.
