WNS-024-0 is a self-locating projection weld nut made of stainless steel for welding onto thin metal sheets, providing internal threads for #10-24 fasteners. It features engineered projections to prevent burn-through and warping, a round head for automatic alignment, and a self-locating shank that protects threads from spatter and eliminates the need for pilot electrodes. The part has a shank diameter of 0.250 inches, a minimum hole size of 0.250 inches, and a minimum distance from hole center to edge of 0.440 inches. Installation requires a 50KVA spot-welding machine with flat-faced electrodes having a tip diameter 0.125 inches larger than the E dimension. The nut meets ASME B1.1 2B thread standards and has a copper flash finish to prevent rust and aid feeding.
PEM® weld nuts (Types WN/WNS) provide load-bearing threads in metal sheets too thin to tap, and permit faster assembly.
PEM brand weld nuts overcome many problems associated with other weld nuts – burn-outs, complicated electrodes and pilots, tedious time-consuming indexing and re-tapping to remove weld spatter. Their design, based on the experience of hundreds of users of weld nuts, speeds production using standard equipment, thereby reducing labor costs.
PEM stainless steel weld nuts offer the added advantage of resisting corrosion. You may specify steel or stainless steel for your requirements and be sure you are getting the weld nuts that are easiest to install. 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.
