Grade 2 Coupling Nut, Plated

These coupling nuts will either conform to SAE J995 Grade 2 or ASTM A563 Grade A, both of which are manufactured from carbon steel and are eequivalent in strength. Dimensional specifications are governed by ASME B18.2.2. Grade markings are not required for either A563 Grade A, or SAE J995 Grade 2 hex coupling nuts. Coupling nuts, also known as extension nuts, are used for joining two male threads, usually threaded rods, in a variety of applications. Available in zinc plated finish. Zinc plating sacrifices itself, corroding before the base material, offering added corrosion resistance.
