The WSM metric weld nut is a square nut with four projections located to provide
proper seating and sturdy positive welds. It also has deep threads for secure engagement
and strength. The WSM weld nut is also countersunk on both sides to guide the mating
screw quickly into the threads. Rounded corners on the WSM weld nut ease use in
confined areas. The WSM is easily fixtured for rapid welding by a locator pin in
the electrode.
