Heavy Hex Nuts


Heavy Hex Nuts

Heavy Hex Nuts are the strongest of all comparably graded designs, both thicker and wider across the flats than standard finished hex nuts of the same size. They are available in a variety of grades and the heavy pattern is typically used for large diameter and high strength bolts. Heavy hex nuts have a greater length of thread engagement and better resistance to stretching or widening.
