Hex Nuts - Heavy

Heavy hex nuts are a six sided internally threaded fastener which is both thicker and wider across the flats than a same sized finished hex nut. Nuts in sizes 7/16 & smaller shall be double chamfered. Larger sizes are either double chamfered or chamfered on top with a washer faced bearing surface.

This is the strongest of all comparably graded nuts because of its greater length of thread engagement and greater resistance to dilation (widening or stretching).
