A square nut is a four-sided nut. 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. They are also much less likely to become rounded-off after repeated loosening and tightening cycles.

Features:
Made of 304 stainless steel material, the 304 stainless steel material provides strength and offers good corrosion resistance in many environments.
Square nuts have a greater surface in contact with the part being fastened, and therefore provide greater resistance to loosening.
