Request 3D Model

Self-Piloted Nut Electrods are designed for projection welding nuts. The part has an insulated, fixed pilot which centers the nut in position. Use with an upper electrode with a hole to receive the pin.

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 2.000 IN
The part mounts via a 5RW standard taper which is suitable for weld forces ranging between 800 to 1500 pounds of force.
The weld face is 1.25 IN
The part has a fixed insulated pilot for welding a 3/8 nut
The diameter of the pin is 0.306 IN
The pilot stickout length from the face of the elctrode is 0.375 IN
