Black Guard™ black oxide treatment typically penetrates .000040″ – .000060″ deep, which will visually reveal wear patterns allowing the inspector to calibrate or replace gage pins more effectively.
Black Guard™ treatment will help prevent rust and corrosion, which will extend the useful life of the gage.
