How much longer service life than ordinary uncoated pins?

Under the same production load, ceramic coated pins can last 3 to 6 times longer than bare metal pins, cutting your spare part cost and production downtime.

Is this pin compatible with all brands of nut welding machines?

Standard M4/M5/M6/M8 sizes fit most mainstream projection welding equipment. If your machine has special structure, we can adjust dimensions for perfect matching.

Product Q&A

Q:What thread sizes do you have for ceramic coated nut welding pins?

Standard stock sizes include M4, M5, M6, M8. We support custom non-standard thread, length and pin diameter upon your requirements.

Q:What is the main function of ceramic coating on welding pin?

The ceramic layer provides good insulation to prevent short-circuit; meanwhile it prevents welding spatter from sticking on the pin, keeping accurate nut positioning and lowering maintenance frequency.

Q:Will the ceramic coating peel off during high-temperature welding?

We adopt high-adhesion spraying process. The coating is compact and crack-resistant, not easy to peel under continuous high temperature nut welding cycles.

Q:Which welding process are these pins suitable for?

Specially designed for projection nut resistance spot welding, widely applied for automotive metal parts, cabinet hardware, electrical appliance nuts welding.

Q:Can I get customized ceramic coated pins?

Yes. We can customize pin length, outer diameter, thread specification and coating thickness based on your samples or technical drawings.
