Coatings on metal fasteners - Specification for mechanically applied zinc and zinc based coatings PAS 15 and metallic paint films are1 Scope This part of BS 7371 specifies requirements for coatings applied by mechanically impacting zinc powder, or zinc based powder on to the component surface in an aqueous medium. The coating is not applied by using impact media accelerated by compressed air or centrifuge methods. The coatings consist principally of zinc and can be lubricated to give controlled torque clamping force properties when required. NOTE 1 See, for example, BS 73712. In
