Square Nut
A Square Nut is a four-sided fastener typically used with bolts, threaded rods, and other externally threaded components. Its larger surface area in contact with the part offers greater resistance to loosening, making it ideal for applications where a strong and secure hold is essential, especially in older machinery, woodworking, and architectural restoration.
