Serviceable post retainer
Disclosed is a push-on fastener to couple a first component to a second component via a post associated with the second component. The push-on fastener includes an annular body, a retention flange, and a release tab. The annular body defines a topside surface, an underside surface, and a retainer opening configured to receive at least a portion of the post. The retention flange is resiliently coupled to the annular body and arranged to engage the post. The retention flange is oriented toward a center of the retainer opening and canted away from the topside surface at a first angle. The release tab is coupled to the retention flange and flexes or to biases the retention flange away from the post to enable removal of the push-on fastener from the post.
