Abstract
According to one embodiment, a fastener includes a shank defined about a central axis and a head coupled to the shank. The head includes a continuous receptacle circumscribing the central axis. The continuous receptacle includes a radially inner surface that is angled radially inwardly toward the central axis in a head-to-shank direction.
Claims18
A fastener, comprising:
- a shank defined about a central axis;
- and
- a head coupled to the shank, the head comprising a continuous receptacle circumscribing the central axis, wherein the continuous receptacle comprises a radially inner surface angled radially inwardly toward the central axis in a head-to-shank direction, and wherein the continuous receptacle comprises an annular shape.
A fastener and installation tool system, comprising:
- a fastener comprising:
- a shank defined about a central axis;
- and
- a head coupled to the shank, the head comprising a continuous receptacle circumscribing the central axis, wherein the continuous receptacle comprises a radially inner surface angled radially inwardly toward the central axis in a head-to-shank direction;
- and
- an installation tool comprising:
- a flexible collet comprising a proximal end and a distal end, the distal end comprising a plurality of projections each matingly engageable with the continuous receptacle;
- a collet flexing portion engageable with the collet to flex the collet to draw the plurality of projections radially inward toward each other.

A fastener, comprising:
- a shank concentrically aligned with a central axis of the fastener;
- and
- a head coupled to the shank, wherein the head extends from a proximal end to a distal end, and the shank extends from a proximal end adjacent the distal end of the head to a distal end away from the distal end of the head, the head comprising at least one receptacle spaced radially outwardly away from the central axis of the fastener, wherein a radially innermost portion of the at least one receptacle extends radially inwardly toward the central axis in a direction away from the proximal end of the head;
- wherein the at least one receptacle comprises an annular-shaped receptacle.
