WN Datasheet PEM® brand WN™/WNS™ weld nuts are designed to be welded onto another metal surface into properly sized holes. The PEM® weld nut design helps overcome many problems associated with other welded nuts: • Engineered projections – Prevent burn-outs in thin sheets – Help keep the nut from warping while welding in high current • Round head design – Eliminates tedious time-consuming indexing – Speeds production using standard equipment – Compact design fits on narrow flanges • Self-locating shank – Eliminates the need for complex electrodes with pilots – Properly positions weld nuts – Protects threads from weld spatter
