Square Nuts

A square nut is a four-sided, internally threaded fastener with a flat bottom side and a chamfered, washer-crowned top. Square nuts are used with a flat washer to avoid damage from sharp edges and helps increase the strength of the overall assembly. Designed for use with square bolts for a rustic look in a new structure or to match existing fasteners in older structures. Available and ready-to-ship in a variety of sizes and finishes.
