  • Method of fastening panels using blind fasteners with engageable drive nuts
    Publication number: 20020164203
    Abstract: A blind fastener of the type having a fastener body, a threaded stem and a sleeve is provided with a drive nut in abutting contact with the fastener body to provide mechanical engagement between the abutting surfaces of the two elements. The underside of the drive nut includes locking elements to drivably engage 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.
