JDM F15 specifies requirements for electroplated zinc coatings for fasteners made of steel. JDM F15 applies primarily to electroplated coatings on threaded fasteners, non-threaded fasteners, and fastener accessories such as pins and washers. JDM F15 may also be applied to other threaded parts where torque tension relationship is important.
