Description

1 Description There are screws existing that can be screwed in and out of steel and wood. The one way security screw has a special head on the screw that allows the screw to be screwed in one direction only. If you try to reverse the screw the head slips and the screw cannot come out. The invention maybe better understood with reference to the illustration of embodiment, isometric view.
