Square Nuts are four-sided threaded fasteners designed to provide a larger bearing surface and greater resistance to loosening compared to hex nuts. Installation involves threading the nut onto a corresponding bolt or screw and tightening it with a wrench or pliers to achieve a secure connection.

Square Nuts are widely used in machinery, construction, furniture, and electrical applications, particularly where higher torque and stability are required. Available in materials such as stainless steel, mild steel, and brass, they offer reliable mechanical strength, corrosion resistance, and long-lasting performance in both indoor and outdoor environments.
