1. A push-on fastener comprising:
a push-on fastener body comprising a substrate comprising spring steel and forming an annular base defining an aperture, first and second opposing major surfaces, and a plurality of radial tabs extending from the annular base, the radial tabs terminating radially inwardly or radially outwardly; and
a low friction layer comprising a polymer overlying and laminated to the substrate, wherein the annular base further defines an inner peripheral surface and an outer peripheral surface opposite the inner peripheral surface, wherein 1) the radial tabs terminate radially inwardly providing the inner peripheral surface, or 2) the radial tabs terminate radially outwardly providing the outer peripheral surface, wherein the low friction layer has an axial height TFL in a range of 0.1 mm and 0.4 mm, wherein the low friction layer is overlying and laminated to the substrate 1) along the first major surface but not the second major surface of the push-on fastener body, or 2) along the second major surface but not the first major surface of the push-on fastener body.
