Finishes & Colors We Offer
Pick the finish that fits your use and budget — corrosion protection, looks, preserved thread size.
Beyond hardness, a part's surface color signals its corrosion protection and use. We color metal through chemical/electrochemical processes that bond in and resist peeling — from multi-color zinc to black oxide to phosphate.
