Product Details

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 wrench 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 often used in small engines.
