Grade 2 Left Hand Thread Hex Nut, Plated

Left Hand Threaded SAE J995 Grade 2 hex nuts are an economical, common low strength nut manufactured from low carbon steel. Grade 2 hex nuts are available in diameters from 1/4" through 1 1/2" inclusive. Dimensional specifications are governed by ASME B18.2.2. Grade 2 requires no material marking. Left hand threads are used in specialty applications to mate with left handed bolts and studs. These nuts are equivalent in strength to ASTM A563 Grade A nuts. Available in zinc plated finish. Zinc plating sacrifices itself, corroding before the base material, offering added corrosion resistance.
