Weld Nuts

A weld nut is a square or hex nut with a flat or projection-bearing face designed to be welded onto a workpiece. Once welded it forms a permanent threaded anchor without access behind the panel.

Used on frames, brackets, tanks and sheet-metal fabrications that need a fixed nut position. Bought by welders, fabricators and equipment manufacturers.
