Regular square nuts in 18-8 Stainless Steel per ASME B18.2.2. Four flats give a wrench or spanner more purchase than a hex and let the nut seat against a channel, slot or timber face without spinning — the traditional choice for strut channel, wood framing, sign and machinery work, and for period-correct restoration. 4 thread sizes (5/16-18–3/4-10). Sold in bulk multiples.
