A fastener includes a body having a cylindrical passage formed through a central portion of the body and a tapered ramp disposed at an end of the body and a corebolt disposed within the passage formed by the body. The fastener further includes a sleeve movably disposed over the corebolt and adjacent the tapered ramp of the body. The sleeve includes a bore extending between first and second ends of the sleeve and a taper extending inwardly from the second end of the sleeve toward the first end of the sleeve, the second end of the sleeve being adjacent the tapered ramp of the body. The sleeve further includes a weakened interior region disposed between the taper and the first end of the sleeve, the weakened interior region being adapted to bulb outwardly when the sleeve is compressed against a workpiece.
