Abstract
A blind tack fastener includes a pull stem having an elongated shaft with an extended tail portion. The blind tack fastener also includes a crush-initiating washer, a crush sleeve, and a swage collar, surrounding the elongated shaft of the pull stem. The elongated shaft has a breakaway groove configured to create a predictive fracture point below the head-end surface of the swage collar, such that a hole in the swage collar serves as a centering lead-in for a drill that can be used to remove the blind tack fastener.
