A fastener comprising: a nut that defines an internally threaded cylindrical bore through said nut along a longitudinal axis, wherein said nut comprises a nut head on a first end, a cylindrical outer surface, an external tapered ramp surface on a second end, an unthreaded cylindrical recess extending from said second end toward said first end, and a first shoulder in said cylindrical bore positioned between the internal threads thereof and said unthreaded cylindrical recess; a bolt (140;240) comprising a bolt head, an externally threaded portion (144;244) threadingly engaged with said internally threaded cylindrical bore of the nut, an enlarged shank (150;250;450) positioned between said externally threaded portion and said bolt head, and a second shoulder (152;252) on said enlarged shank, wherein an outer diameter of the enlarged shank (150;250) is smaller than an internal diameter of the unthreaded cylindrical recess of the nut, and wherein the outer diameter of the enlarged shank is larger than a major diameter of the internally threaded cylindrical bore of the nut and/or or larger than a major diameter of the externally threaded portion (144;244) of the bolt; and a sleeve defining an unthreaded cylindrical bore (176,180), wherein said sleeve is positioned over said bolt between said bolt head and said external tapered ramp surface of the nut, and adapted to form a blind side upset when said bolt is tightened relative to said nut, and wherein said first shoulder and second shoulder (152;252) are adapted to abut and block further movement of said bolt relative to said nut in a tightening direction when the blind side upset is fully formed. a nut that defines an internally threaded cylindrical bore through said nut along a longitudinal axis, wherein said nut comprises a nut head on a first end, a cylindrical outer surface, an external tapered ramp surface on a second end, an unthreaded cylindrical recess extending from said second end toward said first end, and a first shoulder in said cylindrical bore positioned between the internal threads thereof and said unthreaded cylindrical recess; a bolt (140;240) comprising a bolt head, an externally threaded portion (144;244) threadingly engaged with said internally threaded cylindrical bore of the nut, an enlarged shank (150;250;450) positioned between said externally threaded portion and said bolt head, and a second shoulder (152;252) on said enlarged shank, wherein an outer diameter of the enlarged shank (150;250) is smaller than an internal diameter of the unthreaded cylindrical recess of the nut, and wherein the outer diameter of the enlarged shank is larger than a major diameter of the internally threaded cylindrical bore of the nut and/or or larger than a major diameter of the externally threaded portion (144;244) of the bolt; and a sleeve defining an unthreaded cylindrical bore (176,180), wherein said sleeve is positioned over said bolt between said bolt head and said external tapered ramp surface of the nut, and adapted to form a blind side upset when said bolt is tightened relative to said nut, and wherein said first shoulder and second shoulder (152;252) are adapted to abut and block further movement of said bolt relative to said nut in a tightening direction when the blind side upset is fully formed.
