A fastener system including a blind grounding stud and a sleeve. The sleeve has a first section abutting a second section. The first section has a smaller outer surface diameter than the second section. A knurled band is formed around the first section beginning at the intersection between the first and second sections. The sleeve has an opening axially through the two sections. The opening has a first larger inner surface which tapers via a frusto-conical surface to a smaller diameter inner surface. The larger diameter inner surface extends from the free end of the sleeve first section and extends toward the second section to the frusto-conical surface. The smaller diameter inner surface begins at the free end of the second section and extends toward the first section to the frusto-conical inner surface. The smaller diameter inner surface spans at least a portion and preferably all of the knurled band.
A fastener system comprising:
A sleeve for a blind stud comprising:
The sleeve of 18 wherein the opening further comprises a frusto-conical inner surface bridging the first and second cylindrical inner surfaces and providing an annular tapered surface for transitioning from the first cylindrical inner surface to the second cylindrical inner surface.
A fastener system for a panel comprising:
