A heavy hex nut is a six-sided internally threaded fastener which is both thicker and wider across the flats than a same-sized finished hex nut. This is strongest of all comparably-graded nuts because of its greater length of thread engagement and greater resistance to dilation (widening or stretching). Grade 5 nuts are used with medium-carbon cap screws/bolts; Grade A nuts are used with low-carbon heavy hex bolts; Grade C nuts are recommended for use with A-325 structural bolts; Grade-2H nuts are recommended for use with bolts in high-pressure and high-temperature service. Grade-DH nuts are recommended for use with A-490, Type-1 structural bolts and Grade-DH3 nuts for use with A-90, Type 3 structural bolts; 18-8 stainless steel nuts are used with 18-8 stainless steel bolts. Available and ready-to-ship in a variety of sizes, finishes and coatings. Browse our selection of heavy hex nuts for your building projects and industrial applications.
