ASTM A194 GR.8 Hex Nuts

What are Grade 8 Hex Nuts?

A hex nut is a six-sided, internally threaded fastener. The term "grade 8" refers to the strength & hardness of the nut material. Specifically, SS Grade 8 Hex Nuts are made from high-strength steel alloy & are heat-treated to increase their hardness and resistance to wear & tear. ASTM A194 Grade 8 Hex Nuts are heat treated to provide greater strength. These nuts are designed for use with Grade 8 cap screws and have a proof load of at least greater than the minimum tensile strength of the bolt. These nuts are used in heavy industries like heavy machinery, mining, tractors & trucking.
