Inch Size Grade 5 Zinc Cr3 Clear Plate Bolt
Grade 5 fasteners with Cr3 clear zinc plating offer both strength and enhanced corrosion resistance. Made from medium-strength carbon steel, these fasteners are heat-treated to a tensile strength of 120,000 psi. The Cr3 clear zinc plating, which uses a chromium-free process, provides a thin, clear coating that protects against rust and environmental degradation without affecting the fastener’s mechanical properties. This plating is environmentally friendly, as it avoids the harmful effects of hexavalent chromium (Cr6). Cr3 clear zinc also offers excellent wear resistance, maintaining the fasteners' performance while preserving their appearance in applications where corrosion protection is crucial.
