Grade 2 Hex Nut, Galvanized

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.These nuts are equivalent in strength to ASTM A563 Grade A nuts. Grade 2 nuts are commonly used in bolting applications with Grade 2 bolts, Grade 5 bolts, and A307 bolts. Available in hot dip galvanized finish, which provides a corrosion resistant zinc coating.
