Short answer: Black oxide (blackening) converts the surface of steel, stainless or copper into a thin, uniform black iron-oxide layer that reduces glare, improves appearance and adds mild corrosion resistance without changing dimensions or masking threads. It is the standard finish for tools, fasteners, firearms, bearings and instrument parts where a non-reflective, dimensionally stable coating matters more than heavy protection — usually sealed with oil or wax.
