William The drill & tap process you described works great for a good watertight attachment. But does Multi-Contact make the bulkhead style connectors with any thread pitch beside M12x1.5 metric ? Not that a metric tap is a big investment but the attaching using the threaded end with a nut is quicker though not water tight without sealant. Threaded is also easier to remove but the wall thickness ultimately will determine which method to use. This goes the same for wire strain relief 'glands' that come with a confusing choice of thread types- straight, tapered, metric, NPT, PG etc and with or without nuts. Many high volume distributors will send a sample part upon request allowing you to look and measure hole size, thread length and whether the neoprene insert will actually close tight on the wire you plan to put thru it.

William Miller Just yesterday, working with a machinist, we figured out a simple procedure for modifying a 1/2" threaded plug to accept the threaded stud on the back of these connectors. Now we can thread these into 1/2" hubs on bell boxes. Very handy. We have only ordered them in quantities of 100. Good luck, William _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
