5/16-18 non-serrated hex flange nuts in 18-8 stainless steel to ASME B18.2.2, black fluoropolymer finish. The built-in flange spreads the load like a washer and spans oversized or slotted holes, and the smooth bearing face won't dig into painted or finished surfaces. A black fluoropolymer coating adds a black finish and extra corrosion resistance. Sold in production-volume bulk packs.
