Request 3D Model

Non-Piloted Nut Electrodes are for welding nuts. The part has an insulated, spring loaded pilot that retracts when it makes contact with the upper electrode which prevents damage.

A refractory metal face is made of RWMA Class 11 (75% tungsten, 25% copper) (ASTM 702 C1D) is brazed onto the base material. This face is typically used for welding at higher pressure and heat common with projection welding.

The overall length is 1.500 IN
The part mounts via 5/8 - 18 threads.
The weld face is 1.25 IN
The part has a spring loaded insulated pilot for welding a 11 mm nut.
The diameter of the pin is 0.359 IN
The diameter of the pilot is 0.466 IN.
