A dowel fastener for frictionally engaging the sides of recesses, bores or apertures in wood, metal, and/or plastic joint members to hold the joint members together is disclosed. The dowel has a flexible, resilient, compressible tubular body with a spiral slot extending along its length. At least one end of the dowel is tapered and preferably includes inwardly angled, segmented, end flanges terminating in a circular, free end edge of smaller diameter than said body. The flanges lead the dowel into a reduced width or diameter recess or aperture upon assembly into a joint. The opposite end may also be tapered for insertion in a similar recess or include an apertured, planar end preferably formed from bent end flanges for securing the dowel to a surface with a screw or other fastener. Preferably, the diameter of the free end edge of the tapered end or ends is sized to prevent compressive insertion in an aperture or recess which is too small and would otherwise cause deformation or failure of the dowel. |
