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 may be a suitable substitute provided bolt standard allows. 2. 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.

Mechanical Properties of Internally Threaded Fasteners (1): Galvanize coating refers to nuts that have been plated with a plating or coating of sufficient thickness to require overtapping of the nut to provide assembly: for example hot-dip or mechanical galvanizing.
