Square nuts are four-sided fasteners with a flat, large surface area that provides excellent resistance against loosening. They are commonly used in heavy-duty applications where high torque is required. Square nuts are ideal for use with flat washers to prevent damage to the surface and to ensure a tight grip.
These nuts are widely used in construction, machinery, electrical equipment, and furniture fittings. Their large contact surface makes them easier to grip with tools, reducing the chances of rounding off edges compared to hex nuts.
