1. A fastener system comprising:
a bar extending along an axis, the bar including a catch at a first end and a head at a second end, wherein the head includes a first inclined face;
a knob configured to engage with the catch to prevent relative rotation between the knob and the bar and to prevent separation of the knob and the bar along the axis;
a bushing comprised of an elastomeric material that is positioned around the bar between the catch and the head, wherein the bushing includes a flange facing the knob; and
a washer positioned around the bar between the bushing and the head, wherein the washer includes a second inclined face that contacts the first inclined face,
wherein a coefficient of friction between the bushing and the washer is higher than a coefficient of friction between the washer and the head.
