Abstract
A blind fastener of the type having a fastener body, a threaded stem and a sleeve is provided with a deformable drive nut in abutting contact with the fastener body to provide a positive mechanical engagement between the abutting surfaces of the two elements. The underside of the drive nut has an annular ridge made of a deformable material adapted to deform into indentations in the outer surface of the fastener body. The positive mechanical engagement between the two elements minimizes the build-up of tensile load applied to the stem during setting of the fastener.
