Surface Finish

This product has Black oxide (aka blackening) surface finish, which is a coating applied for mild corrosion resistance and to minimize light reflection. Black oxide treated fasteners can rust in the right environments, so it should be stored properly to avoid rusting.

High tensile steels are very strong, but they are prone to rust formation, It can be avoided by keeping the component waxed or oiled and stored in proper boxes.
