Product Description

These hex head screws each feature a thick, hexagonal head designed for tightening with a wrench. Use in pretapped holes or with nuts. Grade 5 steel construction offers strength and moderate flexibility. The screws are hardened, yet more malleable than Grade 8, allowing them to withstand shear force.
