ActiveFasteners—Non-electrolytically applied zinc flake coatings
紧固件 非电解锌片涂层
Application Summary AI generated
This standard specifies the requirements, test methods, and acceptance criteria for non-electrolytically applied zinc flake coatings on fasteners. It is applied in the automotive, construction, and general engineering industries to provide corrosion protection for bolts, screws, and nuts, particularly in environments where hydrogen embrittlement from electroplating is a concern. The standard ensures consistent coating thickness and adhesion for fasteners used in high-stress or safety-critical assemblies.
