Abstract

The helical insert has a plastic interior (3), corresponding to the screw profile (6), extruded over a metal exterior (2) having a series of points (8). The insert is placed in a pre-drilled hole, the inner diameter of the insert being less than the screw's outer diameter. As the screw is screwed into the insert the interference between the two forces the outer metal points into the wood, the points being so shaped to prevent extraction of the insert.
