High retention fastener

A retention fastener, comprising:

• a body panel;
• first and second leg members integrally connected to the body panel by first leg member portions and both co-extending with respect to a first panel face of the body panel and having a second leg member portion directed back toward the body panel, each of the first and second leg members including:
• at least one retention feature connected to the second leg member portion, including:
• a single tooth wing having a smooth first curved surface having a radius of curvature extending to a single wing retention tooth, and
• a multiple tooth wing positioned beside the single tooth wing, the multiple tooth wing having multiple individual teeth arranged on a second curved surface having a radius of curvature equal to the radius of curvature of the first curved surface, the individual teeth sequentially increasing in height with respect to the second curved surface, the multiple tooth wing being oriented in a superimposed position with respect to the single tooth wing such that the height of the individual teeth extend further outward and away with respect to the smooth first curved surface of the single tooth wing.

A retention fastener system, comprising:

• a panel having an aperture created therethrough, the panel having opposed first and second panel surfaces;
• a fastener adapted to partially extend through the aperture of the panel, the fastener including:
• a body panel contacting the first panel surface in a fastener installed position;
• first and second leg members integrally connected to the body panel by first leg member portions and both co-extending with respect to a first panel face of the body panel and having a second leg member portion directed back toward the body panel, each of the first and second leg members including:
• at least one retention feature connected to the second leg member portion, including:
• a single tooth wing having a smooth first curved surface extending to a single wing retention tooth, and
• a multiple tooth wing positioned beside the single tooth wing, the multiple tooth wing having multiple individual teeth arranged on a second curved surface sequentially increasing in height with respect to the first curved surface, the multiple tooth wing second curved surface being in a superimposed position with respect to the single tooth wing first curved surface such that the height of all of the individual teeth extend further outward and away with respect to the smooth first curved surface of the single tooth wing;
• the first and second leg members extending through the aperture in the fastener installed position and having an individual one of the individual teeth of the multiple tooth wing and the smooth curved surface of the single tooth wing of both the first and second leg members contacting the second panel surface.
