Regular square nuts in 316 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. 3 thread sizes (1/4-20–5/8-11). Sold in bulk multiples.
