1. A headlight assembly comprising
a brace formed to include a plurality of openings, a headlamp including a lighting element and a housing, the housing formed to include a plurality of holes arranged to align with the plurality of openings included in the brace, and a plurality of self-adjusting fasteners extending through the openings in the brace and into the holes in the headlamp to couple the headlamp to the brace, the plurality of self-adjusting fasteners configured to self-adjust during mounting of the headlamp so that the headlamp is maintained in a preselected orientation while compensating for irregular spacing between the headlamp and the brace caused by manufacturing variations, each self-adjusting fastener including (i) an anchor having a sleeve with external threads engaged with the brace around the hole and a cap formed to include an aperture, (ii) a drive screw having a head sized to engage the brace around the aperture, a shank, and a shoulder extending from the head to the shank, and (iii) a bushing having external threads engaged with internal threads of the sleeve included in the anchor and an internal feature engaged with the shank included in the drive screw to couple the drive screw to the bushing, wherein the shank of the drive screw is sized to engage the cap of the anchor around the aperture during a first phase of drive-screw rotation so that the anchor is coupled to the drive screw for common rotation when the shank is received in the aperture and the shoulder is sized to extend through the aperture formed in the cap without engaging the cap around the aperture during a second phase of drive-screw rotation so that the drive screw is free to rotate relative to the anchor when the shoulder is received in the aperture. |
