Create Strong Threads Where Ordinary Nuts Can’t Reach
Add a strong thread to thin metal, panels, and hollow tubes. Work from one side only. No welding. No need to remove the panel.
- Works in Tight, Closed Spaces
- Creates a Strong Thread
- Fits M3, M4, M5, M6 & M8 Rivet Nuts
A simple tool for car repairs, metal shelves, trailers, and DIY jobs.

Some Jobs Are Hard for One Simple Reason
You drill the hole and line up the parts. But you cannot reach behind the panel to hold a nut.
The space may be closed, hollow, or too tight for your hand.
Normal screws can come loose in thin metal. Welding or taking the panel apart can turn a small repair into a big job.
This compact tool gives you an easier way.

Turn a Plain Hole Into a Strong Thread
Place the right rivet nut into the hole. Then tighten it with the matching tool.
The tool pulls the rivet nut up. Its lower part folds behind the metal and grips both sides, like a metal sandwich.
Unscrew the tool when you are done. A strong thread is now ready for a normal bolt.
