Abstract
A blind fastener having an internally threaded sleeve with a head at one end and a taper at the other. A mandrel is threaded into and through the sleeve, and has a head that bears against a collar which it pushes onto the tapered end of the sleeve. A nut is threaded onto the mandrel to be turned against the head of the sleeve. In turn, the nut is restrained against rotation by a torque tool, and the mandrel is engaged by the tool to turn them counter-rotatively to set the fastener. The nut has a face that faces toward the head of the sleeve that is adapted to make at least a partially conforming engagement with recesses in the head of the sleeve.
