Abstract
A small frangible device for repairing stripped or damaged holes for reinsertion of a screw or nail while reusing and maintaining the original properties of the fastener and capable of immediate use with minimal preparation. The device is characterized as having a generally elongated rounded exterior surface with a relatively narrow end and an opposite thicker end forming a tapering conical shape with a hollow interior and a textured outer surface further characterized by a plurality of non-contiguous, mis-aligned, raised, semi-spherical bumps.
Claims4
A device for restoring damaged fastener holes in a medium comprising:
- a fastener sleeve having an exterior surface, a substantially hollow interior, a first narrow end, a second opposite thick end, wherein the fastener sleeve is configured to be selectively shortened to fully fit inside a target fastener hole;
- wherein the exterior surface and the hollow interior each taper in decreasing diameter from the second opposite relatively thick end to the first narrow end;
- wherein the fastener sleeve comprises a nub section disposed on its second opposite thick end and a plurality of circumferential scores extending sequentially to the first narrow end configured to allow the fastener sleeve to be snapped into two pieces at a location of any of one chosen circumferential score;
- wherein the fastener sleeve comprises a textured surface on the exterior surface and said exterior surface further comprising a plurality of randomly placed, non-contiguous mis-aligned semi-spherical raised bumps substantially along an entire length of the exterior surface.
A device for restoring damaged fastener holes in a medium comprising:
- an elongated fastener sleeve having an exterior surface, a substantially hollow interior, a first narrow end, a second opposite and thick end, wherein the exterior surface is conical shaped from the first narrow end to the second opposite and thick end and the substantially hollow interior is defined by a tapering conical shape, and the fastener sleeve is configured to be selectively shortened to fully fit inside a target fastener hole;
- wherein the fastener sleeve comprises a nub section disposed on its second opposite and thick end and a plurality of circumferential scores extending sequentially to the first narrow end configured to allow the fastener sleeve to be snapped into two pieces at the location of any of one chosen circumferential score;
- wherein the fastener sleeve comprises a textured surface on the exterior surface and said exterior surface further comprising a plurality of randomly placed, non-contiguous mis-aligned semi-spherical raised bumps substantially along an entire length of the exterior surface.
