conduit devices and wiring devices of the half inch variety actually have a 1/2 inch straight pipe thread. they go into a seven-eighths inch hole [ID] no problems witht the romex clamp. just install it in the KO for the wire, in or next to the wiring cover. leave enough of slack to wire to - six inches is a good length. when you wire nut them fold them easily into the access box, just don't cram them in there. I know for fact #10 wire solid is not the easiest thing to work with.
