USA Heavy Hex Nuts

Offering USA/Domestic make and origin for heavy hex nuts that conform to the ASTM A563 standards with strict quality measurements for Grade C and DH options as well as A194 standards for Grade 2H rating. All of our heavy hex nuts are manufactured from high strength steel that offer high reliability connections for high-stress environments. They are compatible with heavy hex bolts, including those that are also of USA/Domestic origin that conform to similar standards and strengths, so long as the diameter and thread pitch match.

Material certifications available upon request!
