A fastener for a vehicle wheel, comprising:
- a fastener body comprising a thread encircling an axis of the fastener body, a top portion with a plurality of wrenching surfaces disposed around the top portion, a bottom portion with a circular cross-section located below the top portion,
- wherein the bottom portion extends radially beyond the top portion and forms a shelf at the intersection of the top portion and the bottom portion,
- a plurality of projections disposed on the shelf, wherein the plurality of projections extend radially outward beyond the circular cross-section of the bottom portion;
- a cap comprising a wall, the cap disposed over the top portion of the fastener body and partially disposed over the bottom portion of the fastener body, a section of the cap disposed over the bottom portion including a double wall, wherein the double wall section of the cap is located adjacent to the plurality of projections.
A method of assembling a cap onto a fastener body, the fastener body comprising a thread encircling an axis of the fastener body, a top portion with a plurality of wrenching surfaces disposed around the top portion, a bottom portion with a circular cross-section located below the top portion, wherein the bottom portion extends radially beyond the top portion and forms a shelf at the intersection of the top portion and the bottom portion, a plurality of projections disposed on the shelf, wherein the plurality of projections extend axially toward the top portion, the cap comprising a wall with an edge having a double wall section, the method comprising:
- placing the top portion of the fastener body in the cap,
- pressing the bottom portion of the fastener body toward the cap such that the plurality of projections are adjacent to the double wall section of the cap,
- deflecting the plurality of projections radially outward beyond the circular cross-section of the bottom portion of the fastener body.
