5 Compatible denotes commercially available nut having suitable mechanical properties and dimensional configuration or style which will make it possible to obtain the desired bolt load. Higher strength nuts or nuts of equal strength may be a suitable substitute provided the bolt standard allows it. 2. Galvanized nuts are intended for use with externally threaded fasteners that are hot-dip or mechanically galvanized or have a coating of sufficient thickness to require over-tapping of the nut to provide assembly. 3. ASTM A194 2H heavy hex nuts may be substituted for ASTM A563 DH heavy hex nuts. 4. Grade 2 requirements for sizes 1/4 through 3/4 in apply only to bolts and screws 6 in.
