Bibliography
Defines dimensional requirements for electroplated fasteners of steel or copper alloy. Defines thicknesses of coating and provides recommendations for hydrogen embrittlement relief for fasteners having high tensile strength or hardness and for surface-hardened fasteners. Deals mainly with the electroplating of threaded fasteners, but may also be applicable to other threaded parts, and nonthreaded eg. washers and pins.
