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 relatively narrower end, a second opposite and relatively thicker 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 thicker end to the first relatively narrower end;
- wherein the fastener sleeve comprises a nub section disposed on its second opposite thicker end and a plurality of circumferential scores extending sequentially to the first relatively narrower 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 non-contiguous raised bumps between at least some of said circumferential scores.
1 more element
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 relatively narrower end, a second opposite and relatively thicker end, wherein the exterior surface is conical shaped from the first relatively narrower end to the second opposite and relatively thicker end and the substantially hollow interior is defined by a correlatively smaller 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 thicker end and a plurality of circumferential scores extending sequentially to the first relatively narrower 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 non-contiguous raised bumps between at least some of said circumferential scores.
