About This Item

 

Full Description

This specification covers the requirements for the coating, part performance, quality, KCC, source approval and quality control, packing, shipping, and identification, and designation on drawings.

**Note** this specification is only for fasteners! See MPAPS G-9009 for cathodic electrocoat (e-coat) requirements associated with all non-fastener parts.

RESTRICTED CHEMICAL SUBSTANCES

All product supplied to the requirements of this specification must comply with the requirements of the MPAPS B-50 specification.

APPLICATION

This specification is for a black non-decorative corrosion-resistant finish consisting of zinc plating with a black cathodic electrocoat (e-coat) as applied to Fasteners. This type of finish is intended for exterior applications requiring good corrosion resistance, but not requiring UV resistance, such as for underhood or non-visible/non-exposed chassis parts. Fastener applications might include fasteners size M6 and larger, thread formers, tapping screws, some SEMS screws, and hex flange bolts. This coating should not be used on small machine screws (less than M6) or on washers.
