摘要

A fastener for installation into an interference fit hole within a structure. The fastener may be installed through automated installation methods. The fastener includes an enlarged protruding head at a proximal end of the fastener. Distal the head is a substantially cylindrical shoulder portion. The shoulder portion is coated with a lubricant to facilitate insertion of the shoulder portion into the interference fit hole within the structure.
