A tool for installing a blind fastener including a bolt and a nut, the tool comprising:

• a collet disposed about an axis, the collet being configured to selectively engage a tool engagement portion of the nut, the collet including a plurality of fingers;
• a socket assembly including a socket housing and a plurality of rollers, the socket housing defining a bore disposed about the axis, the rollers being spaced circumferentially about the axis, a surface of each roller being configured to engage a cylindrical tool engagement portion of the bolt within the bore to rotate the bolt about the axis;
• a drive body coupled to the socket housing and configured to rotate the socket housing about the axis;
• and
• a mode clutch operable in an engaged mode in which the socket housing is coupled to the collet for common rotation about the axis and a disengaged mode in which the socket housing is rotatable relative to the collet, the mode clutch includes an input member coupled to the drive body for common rotation about the axis and an output member coupled to the collet for common rotation about the axis, the output member being disposed about the input member and axially movable relative to the input member between a first mode clutch position and a second mode clutch position, wherein in the first mode clutch position, the input member is engaged with the output member for common rotation about the axis, and when in the second mode clutch position, the input member is rotatable relative to the output member.
