Square Nuts , 300 Stainless (A1,A2, 18-8,304,310 etc.) (ASME B18. 2.2)

Square Nuts are just four-sided nuts, but compared to standard hex nuts, square nuts have a greater surface in contact with the part being fastened, and therefore provide greater resistance to loosening. Square nuts are typically mated with square-headed bolts.
