The hex head cap screw is a common fastener in construction and machine assembly. The screw head is designed to fit a ratchet or spanner torque wrenches allowing you to tighten the screw to your exact specifications.

Hex head cap screws are typically used to create a bolted joint, in which a threaded shaft exactly fits a corresponding tapped hole or nut.

Grade 2 screws tend to be used in construction for joining wood components.

Grade 5 screws are used in small engines.

Grade 8 screws provide high tensile strength.

One advantage cap screw fasteners have over welds or rivets is that they allow for easy disassembly for repairs and maintenance
