I've got some aluminum pool copeing that I need to bond, does it sound reasonable to try to drill and tap 10/32 machine srews for this . I would have used a screw and nut but the concrete contractor already laid the wire and theres no way to get underneath to put the nut on. The only problem I see is the material thickness is only .062, will only get 2 threads in it. Anybody here no if there's a minimum number of threads that need to be cut. Thanks much.
