This specification covers the basic physical requirements and test methods for phosphate/oil and phosphate/organic corrosion protective coatings for fasteners such as nuts, clips, washers, and other ferrous threaded and non-threaded fasteners that require corrosion protection. The zinc phosphate treatment and subsequent protective coatings are classified into seven grades according to the following requirements: Grade 0A consists of a zinc phosphate coating with no additional sealer (dry); Grade 0B consists of a zinc phosphate coating with a dry organic sealer; Grades 0C, 0D, and I consist of a zinc phosphate coating with supplemental protective oil type compound; and Grades II and III consist of a zinc phosphate with a supplemental zinc-rich epoxy resin coating (with the addition of a clear organic topcoat for Grade II). These coatings may or may not have a decorative finish. The coatings shall meet the requirements specified for appearance, adhesion, corrosion resistance, coating flexibility, thread fit, and dry-to-touch characteristics. In addition, they shall also undergo humidity and coating thickness tests.

1.1 This specification covers the basic requirements for seven grades of corrosion protection for fasteners. Grade 0A consists of a zinc phosphate coating with no additional sealer (dry), Grade 0B consists of a zinc phosphate coating with a dry organic sealer, Grade 0C, Grade 0D, and Grade I consist of a zinc phosphate coating with supplemental protective oil type compound, and Grades II and III consist of a zinc phosphate with a supplemental zinc-rich epoxy resin coating (Grade II includes a clear organic topcoat).

1.2 This specification is intended primarily for fasteners such as nuts, clips, washers, and other ferrous threaded and non-threaded fasteners that require corrosion protection.

1.3 These coatings may or may not have a decorative finish.
