Abstract:
1. A collet for a fastener installation tool, comprising; a pull section with a fastener engagement end, a second end opposite the fastener engagement end, a longitudinal axis extending from the fastener engagement end to the second end, and a plurality of teeth, wherein the pull section is adapted to engage a pull portion of a pin member such that the plurality of teeth is structured to complementarily engagement pull grooves of the pull of the portion of the pin member, wherein the plurality of teeth includes a first tooth located proximate to the fastener engagement end; a bore including a first inner diameter defined by the first tooth of the plurality of teeth, and a second inner diameter defined by each of the remainder of the plurality of teeth, wherein the first inner diameter is greater than the second inner diameter; and a protrusion extending from the fastener engagement end of the pull section and including a first face having a flat circular-shaped surface located ahead of and adjacent to the first tooth and extending within a first plane that is pendicular to the longitudinal axis, a flat second face extending obliquely relative to the longitudinal axis beyond and away from the first face in a direction towards the fastener engagement end, a flat, circular-shaped third face located adjacent to the second face and extending within a second plane that is parallel to the first plane, and a flat fourth face extending obliquely relative to the longitudinal axis in a direction away from the fastener engagement end and extending from the third face and ending at a line of intersection with an outer diameter of the pull section and the first face.
