Title
(EN) PUSH-ON FASTENER, ASSEMBLY, AND METHOD OF MAKING AND USING THE SAME
(FR) ÉLÉMENT DE FIXATION À PRESSION, ASSEMBLAGE, ET PROCÉDÉ DE FABRICATION ET D'UTILISATION ASSOCIÉ
Abstract
(EN)
A push-on fastener (100) including a push-on fastener body (102) including an annular base (104) defining an aperture, first and second opposing major surfaces, and a plurality of radial tabs (110) extending from the annular base (104), the radial tabs (110) terminating radially inwardly or radially outwardly and providing a peripheral surface; and a low friction layer overlying the first major surface of the push-on fastener body, wherein the peripheral surface is free of low friction layer.
(FR)
L'invention concerne un élément de fixation à pression (100) comprenant un corps de fixation à pression (102) comportant une base annulaire (104) définissant une ouverture, des première et seconde surfaces principales opposées, et une pluralité de languettes radiales (110) s'étendant à partir de la base annulaire (104), les languettes radiales (110) se terminant radialement vers l'intérieur ou radialement vers l'extérieur et procurant une surface périphérique ; et une couche à faible frottement recouvrant la première surface principale du corps de fixation à pression. La surface périphérique est exempte de couche à faible frottement.
