Square Nuts

Square nuts are typically used with a flat washer to avoid damage, increase the strength of the assembly, and provide excellent fastening capabilities. They feature a chamfered, washer-crowned top and an internal thread. Square nuts are often applied with square bolts to create a rustic aesthetic or in older, pre-existing structures. Their large surface area resists tightening or loosening during use.
