Nut and Stud Welding Electrodes IN-STOCK at Weld Systems Integrators
Tuffaloy nut and stud welding electrodes IN-STOCK and available for immediate purchase from Weld Systems Integrators. We are a master distributor, maintaining an inventory of Tuffaloy products at our Warrensville Heights, Ohio location for quick shipment and delivery.
Stud Electrodes
Tuffaloy stud welding electrode tips are for projection-welding screws, bolts or pins, whether they pass through the sheet or are to be attached directly to its face.
Nut Electrodes
Tuffaloy projection weld nut electrodes are designed for either self-piloted or non-piloted nuts. The pilots of the non-piloted-nut electrodes are spring-loaded so they can’t interfere with the contacting of nut and sheet under welding pressure.
