Abstract
A fastening system for securing an article to a base uses a conventional drive fastener. A reaction surface on the article contacts the bearing surface on the underside of the fastener head causing the fastener head to tilt relative to the body of the fastener. The reaction surface also causes the body of the drive fastener to deform when it is fully driven into the article, and a portion of the material from the reaction surface is displaced into the aperture to increase the retention force of the fastener.
