Abstract: A blind fastener with an improved drive nut and assembly process. The blind fastener includes a screw, a sleeve, a nut, and a drive nut. The drive nut has a smooth bore and protruding nibs that mate precisely with a driving recess located in the nut head. A side portion of the drive nut is deformed to retain the drive nut on the screw against the nut. Once the new assembly process for the blind fastener has been completed, the drive nut will have been mated with the nut head to prevent any rotation of the nut during installation of the blind fastener. The assembly process includes placing the sleeve over the threads of the screw to a position adjacent the screw head. The nut is then threaded onto the screw adjacent the sleeve. The protruding nibs of the drive nut are next aligned and physically engaged into the driving recess of the nut head by sliding the smooth bore over the screw.
