Collet for a low swage load fastening system

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.
