The fasteners including the a563 grade a heavy hex nut are used as either general structural and mechanical uses for externally threaded parts. Materials of this specification i.e. ASTM A563 2H Structural Nuts have to not only be tested but the individual grades, need to conform to specified values of the material. For instance, the astm a563 grade a coupling nut must conform to values such as hardness and proof load, in addition to the previously mentioned chemical, and mechanical requirements.
The atmospheric corrosion resistance of these astm a563 grade dh equivalent steel fasteners tend to be substantially much better in comparison to that of carbon steel grades, especially those with or without the addition of copper. When properly exposed to the atmosphere, this steel A563 Grade A Nut could be used bare or simply uncoated for many applications.
