摘要
The screw mounting with expanding socket secures an item in position clear of a wall. The screw has a centring point(1) engaging in the socket(4) and integral with the screw. The point can be a relatively long cone with proportions of 5:14-16, and the screw shank(2) can have roughly the same external dia. as the socket. Both screw and socket can be relatively long, to accommodate a distance piece(5) round them, the distance piece being typically a coil spring.
