Product Details

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. As an alternative to welds or rivets, cap screw fasteners offer easy disassembly for repairs and maintenance.

Grade 9 screws are manufactured with high-grade, AISI 8640H alloy steel. The steel is reinforced with alloying elements for added tensile strength. It is generally more responsive to heat and mechanical treatments than plain carbon steels.
