Proposes requirements for electroplated coatings of zinc applied either by barrel plating or other techniques on fasteners with imperial threads (the UNC, UNF and Whitworth series). Two thickness ranges are specified for coatings. The average thickness is calculated from total weight of deposit and total surface area. Appendices give data for the calculation of surface areas of fasteners and nuts having various types of imperial threads and also recommended sampling procedures, information on the effect of manufacturing tolerances on plating thickness calculations and information on heat treatment procedures. Data for thread modification when thicker coatings are required, is included.
