Greetings,

I have a lead battery clamp with a threaded hole that I want to put a stud into. Can I just solder a piece of steel threaded rod into the lead hole??

I'm guessing brass or bronze would be better, but I've got the steel in stock.

Any guidance on doing it, if it's acceptable, would be appreciated.

I would put in an insert then install the stud. There are a few different kinds available, some that screw into the hole and others that go in and expand like a pop rivet. Cabinet workers use the screw in type that have barbs to keep them from unscrewing. (available at your local hardware store)

Thanks for the reply Roger.

I was concerned about a good electrical connection in addition to mechanical strength, that's why I was looking at soldering.

I took the leap and soldered the steel threaded rod into the lead clamp. The rod went into a threaded hole that a setscrew was removed from. I cleaned the rod with a wire wheel and then acetone. Applied rosin flux to the threads and screwed it in. Using a propane torch I heated the rod until the solder wicked down into the threads. The clamp configuration provided a compartment under where the rod threaded in, which I filled with solder to increase the contact area between the rod and the clamp.

Initial inspection and testing showed a strong bond. This is consistent with how strongly a few droplets of solder adhered to the rod.

A standard multimeter shows no resistance.

The the major concern with this process was caused by the plating on the rod. I'm assuming it was either zinc/cad or galvanizing, based on the yellow/white residue from the heating. Heating either of those substances releases toxic fumes and they SHOULD NOT be inhaled. For further info research welding galvanized steel. A minor concern was possible lead vapor from the heating of the clamp.

In summary, it worked exactly the way I wanted. I will be keeping an eye on this and report any noteworthy developments.
