PEM brand self-locating weld nuts feature engineered projections, round head design and a self-locating shank WN SELF-LOCATING PROJECTION WELD NUTSSELF-LOCATING PROJECTION WELD NUTS 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 Round head Eliminates tedious time-consuming indexing Speeds production using standard equipment Compact design fits on narrow flanges Self-locating shank Engineered projections Self-locating shank Eliminates the need for complex electrodes with pilots Properly positions weld nuts Protects threads from weld spatter A variety of welding equipment is suitable for installation of PEM weld nuts. Best results have been obtained with a 50KVA press-type, spot-welding machine whose upper welding head moves vertically in a straight line with the lower electrode. Flat-faced electrodes with tip diameters .125 / 3.2 mm larger than the E dimension of the PEM weld nut should be used. PEM weld nuts are available in steel (WN) or stainless steel (WNS). Stainless steel nuts offer the added advantage of corrosion resistance.
