Coatings on metal fasteners - Specification for phosphate or phosphate and oil coatings Ingestion-build-52208 induced cracking1 Scope This Part of BS 7371 specifies requirements for phosphate or phosphate and oil coatings on metal fasteners and accessories, applied by immersion or spraying. NOTE 1 Phosphate coatings are primarily intended for application to ferrous, zinc or zinc alloy fasteners. NOTE 2 Phosphate coatings can be used as an undercoat to improve the corrosion resistance and adhesion of a subsequently applied top coat (e. g. organic coating). NOTE 3 Phosphate
