Grade 5 Hex Head Cap Screw with Yellow Zinc Cr6 Plating – Strength Meets Style for Inch-Sized Applications
The Grade 5 Hex Head Cap Screw with Yellow Zinc Cr6 Plating is the perfect fastener for applications requiring enhanced strength, a visually distinctive finish, and reliable corrosion resistance. Manufactured to meet SAE standards and available in inch sizes, this cap screw is a workhorse in automotive, machinery, and industrial construction projects where consistent performance matters.
Made from medium carbon steel that's heat-treated, this Grade 5 fastener provides a minimum tensile strength of 120,000 PSI, making it tougher than standard Grade 2 fasteners. Its hex head design allows for easy installation with standard wrenches or sockets, delivering secure clamping force and torque transfer in high-vibration assemblies.
The Yellow Zinc Cr6 plating offers both function and form—providing moderate corrosion resistance and a bright, golden appearance that's easy to identify. This trivalent chromium finish is ideal for indoor or semi-exposed applications and helps reduce galling while offering a lubricious surface for smoother installation.
