Abstract
Blind fasteners are used to connect two or more workpieces together, and are particularly useful in aerodynamic designs. In such uses, it is very desirable to have a substantially flush surface. The present fastener comprises a fastener body having an axial bore therethrough and an enlarged head, a corebolt passing through the axial bore, the corebolt having a first portion, a threaded second portion, and a localized weakened region therebetween, a drive nut configured to fit around and threadingly engage the first portion of the corebolt, and a stop member that substantially prevents further withdrawal of the corebolt relative to the drive nut after the corebolt has been driven a predetermined distance during installation to shear the corebolt at the weakened region.
