China Galvanized Steel Square Nuts

A square nut is a four-sided nut. Compared to stanard hex nuts, square nuts have a greater surface in contact with the part being fastened, and therefore provide greater resistance to loosening(though also greater resistance to tightening). They are also much less likely to become rounded-off after repeated lossening/tighting cycles. Square nuts are typically mated with square-headed bolts. Square nuts are used along with flat washers in order to avoid damage from its sharp edges and help to increase the strengh of the fastener.
