Hex Head Cap Screws Grade 8 Steel Plain 3/8-16 x 1-3/4 are high-strength fasteners designed for demanding assemblies in automotive, machinery, and industrial equipment. With a plain, uncoated finish, these screws provide reliable performance where coatings are undesirable or when a custom finish is applied later.

Crafted from Grade 8 steel, these hex head cap screws deliver excellent shear and tensile strength for secure, long-lasting joints. The 3/8-16 UNC thread ensures compatibility with standard fastener systems, while the 1-3/4 inch length provides versatile engagement in thick materials.

Key features
