Square Nuts - Hot Dipped Galvanized

• Four-sided square nut
• Offers greater resistance to loosening
• Square nuts have more contact with the surface of the fastener and are used with a flat washer to avoid damage from sharp edges
• Hot dipped galvanized steel offers superior corrosion resistance and is well-suited for use in harsh environments
• Hot dipped galvanized products should only be used with fasteners of the same material

Description

Square nuts can be used in a channel or welded to other steel products. 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 (though also greater resistance to tightening). They are also much less likely to become rounded-off after repeated loosening/tightening 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 helps to increase the strength of the fastener.
