ISO4161 304 316 Grade A4-70 M20 Stainless Steel Nut
FLANGE NUTS. Flange nuts are hex nuts with a bottom circular flange that is larger than their top hex section. There are two types commonly available: flange lock nuts, which are prevailing torque type lock nuts, and serrated flange nuts, which are free spinning but have a serrated bearing surface to grip the mating surface.
