TUFFALOY NUT AND STUD WELDING
Stud Electrodes -Tuffaloy stud 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 cannot interfere with the contacting of nut and sheet under welding pressure.

TUFFALOY NUT AND STUD WELDING
The various types and syzes of TUFFALOY stud-and-nut welding electrodes and holders are described below and elsewhere. For excessive wear applications any of these electrodes may be ordered with refractory metal facings, such as TUFFALOY 10W.
