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.

摘要： A fastener installation tool including an upper jaw having a head adapted to engage a fastener for securing a plurality of workpieces to one another, a lower jaw, and first and second pairs of links fastened to the upper and lower jaws. The tool includes a hydraulic cylinder having one end attached to the lower jaw and a piston rod attached to the first pair of links. The cylinder actuates the tool between a disengaged position, in which the links are in a retracted position and the upper jaw and the lower jaw are juxtaposed with one another, and an engaged position, in which the links are in an extended position and the upper jaw and the lower jaw are spaced apart from one another. The tool is adapted to install the fastener to the workpieces when the tool is in its engaged position.

摘要： A fastener and a joint including the fastener, wherein the material in which the fastener is set is a composite. The fastener has a shank with an external helical rib that makes a slightly tighter than net to a moderate interference fit in a cylindrical wall of the hole. The rib has a form whose maximum radial protrusion is flat or convex, and which extends away from its maximum protrusion as a convex curve, devoid of sharp cutting edges. Voids between the convolutions of the rib are adequate to receive displaced material of the hole wall.
