Fastener Surface Conversion

Fastener Surface Conversion

Fastener surface conversions are a method of corrosion prevention with other added benefits. Surface conversion changes the outer surface of the fastener itself either for protection or to create a colour change. These are called chemical conversions which modifies the passive oxide layer or impregnate into the surface.
