Hex Head Cap Screw (ASME 18.2.1)
Hex Cap Screws are hex headed fasteners with external machine screw threads and differ from hex machine bolts by having a washer surface on the underside or bearing side of the head and a chamfered thread end. Hex cap screws have tighter dimensional tolerances than bolts. Metric hex cap screws are specified by various DIN, ISO and JIS standards, and US/Imperial hex cap screws are dimensionally specified by the ASME B18.2.1 specification.
