Heavy hex nuts in 316 Stainless Steel per ASME B18.2.2 — the heavy pattern is wider across the flats and thicker than a finished hex nut of the same thread, giving more bearing area and thread engagement for structural, anchor-bolt, flange and other high-load joints. 13 thread sizes (1/4-20–2-4.5). Sold in bulk multiples.
