Abstract

The device, which is applicable to screws for joining wood or metal is formed from a bolt or screw with an enlarged head with a central hole, at the bottom of which is a hexagonal socket for tightening the screw. A plug fits in the central hole and is retained by a spring ring which fits in a circumferential groove in the screw head and a matching groove in the plug. The plug fits flush with the surface of the head of the screw, and the head fits in flush in a recess in one part.
