Posted: Tue Sep 10, 2013 12:20 am Post subject: soldering steel stud into lead clamp.

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 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 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.
