A blind fastener installation tool which accomplishes the blind installation of a series of fasteners is described in detail in this specification. The blind fastener installation tool comprises a structural housing which features a means for securing a fastener installation assembly in position relative to said structural housing during the blind installation of a fastener; and a means for reciprocating said fastener installation assembly relative to said structural housing at the conclusion of a cyclic blowline-fed or clip-fed blind installation of a fastener. The blind fastener installation tool also comprises a fastener installation assembly comprising (1) a pull rod assembly comprising means for pulling a first portion of a fastener; (2) an annular, piston-actuated, direct action, piston-decoupled pull rod actuation assembly to translate the pull rod assembly relative to said fastener installation assembly when said fastener installation assembly is secured at a fastener installation assembly fastener installation position, thereby pulling said first portion of said fastener until blind installation of said fastener is complete; and (3) a nose assembly comprising (3a) a fastener receptacle for securing the position of a fastener relative to said nose assembly during blind installation of said fastener; and (3b) one or more optional pull rod translation dampening assemblies to smoothly and effectually dampen the sudden translation of said pull rod assembly after pintail break during blind installation of a pintail-break-type fastener. The blind fastener installation tool also comprises an optional fastener delivery assembly, said optional fastener delivery assembly constituting: (1) a clip-fed fastener delivery system; or (2) a blowline-fed fastener delivery system.
