Hex Cap Screws & Hex Bolts

2,604 products

Hex cap screws and hex bolts are used interchangeably but there are minor differences. Hex cap screws feature a washer face underneath the head, a chamfered point, and is installed by turning the head of the bolt into the mating surface. Hex bolts have a flat surface underneath the head, a flat point, and requires a nut to be installed. Both are used in similar applications in construction and machine assemblies.
