ABSTRACT:
A fastener for securing a panel to a substrate is herein disclosed. The fastener has a body portion that is received in a substrate and a pin portion that is passed through a panel and driven into the body portion to secure the panel to the substrate. The body portion has a pair of legs that act to retain the body portion within the substrate and which incorporate an interference control mechanism that controls the force required to insert the pin portion of the fastener into the body portion. The interference control mechanism may include a bore formed through a leg of the body portion, a reduced cross-sectional area formed adjacent the base of a leg at the fastener, or an elastomeric member molded into the base of a leg of the fastener.
