The dual wheel stud remover is used to remove the 13/16 inch flanged square drive inner cap nuts, which secure the inside dual wheels on trucks and trailers. Frequently the square head becomes stripped making it impossible to remove with sockets or wrenches.
To use this 30165 stud remover, simply drive the stud remover over the 1- 1/8 inch threads of the inner cap nut with a soft-faced non-metal dead blow hammer. A series of heat-treated self-tapping splines cut into the threads of the cap nut. Use a standard 1-1/2 inch socket or wrench to unscrew the stripped inner cap nut. After removal, the stripped cap nut may be forced out of the 30165 socket with a punch or drift pin inserted through the hole in the back of the socket.
