Unique PEM design prevents burnouts and eliminates the need for indexing and retapping to remove weld spatter. Thread sizes M3 to M6.
PEM weld nuts overcome many problems associated with other weld nuts such as burn-outs, complex electrodes, time-consuming and re-tapping to remove weld spatter. 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 3.2 mm larger than the "E" dimension of the PEM weld nut should be used.
