Compliance and Restrictions



The hex head cap screw is a common fastener in construction and machine assembly. The screw head is designed to fit ratchet or spanner torque wrenches for tightening to exact specifications. As an alternative to welds or rivets, cap screw fasteners offer easy disassembly for repairs and maintenance. Grade 5 screws are generally used in small engines.

These screws are manufactured with carbon steel, which offers strength, magnetic properties, and malleability.
