ASME B18.2.2 hex nut selection guide

Use diameter, UNC or 8UN thread, ASTM A563 Grade A or B and finish to select the required product. Every product page provides the dimensional limits and theoretical mass for that exact variant. Jam, heavy hex, square, flange, coupling and machine-screw nuts are separate product forms and are not mixed into this category.
