A square nut is a four‑sided fastener designed primarily to resist rotation when tightened. Its flat, broad surfaces provide increased friction against the mating part, making it ideal for applications where access is limited to one side or where vibration could loosen a standard hex nut.
Square nuts are commonly used in switchgear, electrical enclosures, and machinery assemblies—often inserted into a molded slot or welded onto a component to create a stable, anti‑rotation threaded base. They can be manufactured by cold heading (for high‑volume production) or machining (for precision or larger sizes), typically from carbon steel, stainless steel, or brass, with surface treatments such as zinc plating for corrosion resistance. The square shape also allows easy sliding into T‑slots or channels, enabling adjustable positioning in furniture, automation rails, and modular structures. Custom dimensions and thread specifications are supported for different applications.
