Your cart is empty.Square nuts are similar in function to hex nuts, but are 4-sided instead of 6-sided. This shape increases the contact surface, which can help to prevent loosening in certain applications. They are sometimes used in tight spaces since the square shape allows them to be tightened using pliers. Another application is use in metal channels.

this was a difficult product to find, NOT common, worked great as i welded it to a bracket, the square shape and thickness made it easy to MIG weld without buggering up the internal threads.

These zinc coated square nuts worked great, I removed the zinc and made them look old to fit in with my blacksmith shop.
