摘要： A blind fastener for securing a plurality of workpieces is provided that has a sleeve, and a pin member. In an alternate embodiment, the blind fastener has a sleeve, a pin member and a nut. The sleeves have a head with a plurality of rearwardly sloping recesses disposed therein. The recesses are adapted to be engaged with a plurality of rearwardly sloping nibs disposed on one end of a nose secured to an installation tool. The pin members have a splined head adapted to be engaged with a splined driver secured to an installation tool. Use of the splined head on the pin member, the splined driver, rearwardly sloping recesses on the sleeve, and rearwardly sloping nibs on the nose eliminates camming out of the nibs from the recesses during installation of the blind fastener. A nose assembly for installation of the blind fastener is also provided.
