Does anyone know where I can buy an NPT pipe thread hole plug with a hex socket head? I have seen them in aluminum cettified parts before, but Spruce and Wicks only have the square head type and I need one that will not protrude from the hole. I can get them in brass with a socket head from the hardware store, but for this application I really want them in aluminum.
