The socket is a metal piece with an inside thread on one end and an outside thread on the other end. You commonly see them on serial connectors usually on the equipment the cable attached too.
The bottoming out I was refering too was it you use a standoff you may have too much exposed thread on the screws. They will meet inside the standoff before the connectors are properly seated.
