HD Self-Piloted-Nut Electrodes
Tuffaloy Heavy Duty Self-Piloted-Nut Electrodes have a fixed pin for positioning the nut during welding. The parts have an optional 10W weld face to improve the electrode life.
The Heavy Duty Self-Piloted-Nut Electrodes are designed for use with Tuffaloy's Heavy Duty Stud-Nut Holders which are suitable for high forces used for projection welding.
The parts have a large diameter taper available in two sizes:
- HD Size 1 with a 1.00 IN diameter weld face
- HD Size 2 with a 1.50 IN diameter weld face
