Clinch Nut Installation

[GG Allenwrench]

How are the D shaped clinch nuts installed?
I need to replace several 10-32 Clinch nuts in the top of the door of my 1928 Coupe. The nuts are removed and I have new clinch nuts, but no idea how to get them to "clinch".

We buck then in with a rivet gun and a flush rivet tool, ....or in areas where we cannot get directly behind it, we will TIG weld them in on the front side.

Brent doing this now do you install a bolt and then tig, I have a mig wanted to spot weld then dress the area, my fear is i will melt the threads in the d nut thanks al

It does not take much to weld them in place. If your MIG is set right and you use an autodarken helmet you should be fine. I put a few in with a mig as I could not set them with a hammer. I did not get a TIG till much later.

Keep in mind that they are covered on the face. They do not have to be picture perfect to function and they are always covered.

Stick a brass bolt through them to protect the threads while you weld.
I used a MIG welder, just 2 or three little tack welds on each.

This may sound stupid but make sure they are steel.

I got some that turned out to be plated brass or bronze and melted as soon as I hit them with the Tig, I ended up just soldering them in.
