Abstract
A fastener comprises a body having an enlarged head at a first end, a tapered ramp at a second end, a cylindrical shank disposed between the enlarged head and the tapered ramp, and a passage extending between the first and second ends and including threads. The fastener further includes a generally cylindrical corebolt disposed within the passage of the body and having an enlarged head, a breaking groove, and a stop shoulder that is configured to cause an abrupt increase in resistance to threading the corebolt into the body when the breaking groove is substantially flush with an outer surface of the enlarged head. A grip compensator is disposed on the corebolt in abutment with the enlarged head of the corebolt. A deformable sleeve is movably disposed over a portion of the corebolt and disposed between the grip compensator and the tapered ramp of the body.
