Nut Installation via Projection Welding | High-Strength Connection
We install nuts via projection welding for connection points that need to carry high loads.
What Is Weld Nut Installation, and How Does It Differ from PEM?
Weld nut installation welds specially projected nuts to the sheet surface using electrical current. Compared to PEM fasteners, it creates a connection point suited to thicker material and higher tensile/torque loads.
When to Choose Weld Nuts
For parts carrying high mechanical loads — vehicle chassis, machine bodies — typically over 2 mm thickness, weld nuts are the more suitable solution.
Application Range
| Nut Size | Material Thickness |
|---|---|
| M4 – M12 | 2 mm and above |
Which Process Does It Follow?
Applied as part of the bending or welded assembly process, at the assembly stage.

Frequently Asked Questions
Should I use weld nuts or PEM?
Weld nuts suit thicker (2 mm+) parts with high mechanical load; PEM suits thinner parts.
Which nut sizes can you weld?
M4 to M12.
Is weld nut installation an extra cost?
Yes, priced as a separate operation; just mention part quantity when requesting a quote.
