25 March 2020

This specification is approved for use by all Departments and Agencies of the Department of Defense

additional requirements, such as plating composition and torque/tension behavior of the plating on

surrogate threaded fasteners. Although developed for threaded steel fasteners, this plating may be

used on other steel products. While other plating thickness and supplementary treatment options

are available for unique applications, the requirements of this specification are limited to the

ASTM F1941/F1941M codes specified herein. This specification is intended for use on new fasteners

and fasteners which previously may have specified coatings containing cadmium or hexavalent

chromium, substances which have been added to the Aerospace and Defense Declarable Substances

List ("AD‐DSL").
