A tool for installing a blind fastener including a bolt and a nut includes a collet, a socket assembly, a drive body and a mode clutch. The collet is configured to selectively engage a tool engagement portion of the nut. The socket assembly includes a socket housing and a plurality of rollers. The socket housing defines a bore disposed about the axis. A surface of each roller is configured to engage a cylindrical tool engagement portion of the bolt within a bore to rotate the bolt about an axis. The drive body is coupled to the socket housing and configured to rotate the socket housing about the axis. The mode clutch is 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.

A blind fastener includes a bolt and a nut. The bolt includes a shaft, a bolt head, and a lug. The bolt head being disposed between the shaft and the lug and extending radially outward from the shaft. An end of the shaft opposite the bolt head defining external threads. The lug includes a first tool engagement portion, a first frangible portion, and a rim. The rim extends between the first tool engagement portion and the first frangible portion and extends radially inward of the first tool engagement portion. The nut includes a sleeve, a nut head, and a handling member. The sleeve defines a central bore configured to receive the shaft and defining internal threads configured to mate with the external threads. The nut head defining a recess configured to receive the bolt head. The handling member includes a second frangible portion and a second tool engagement portion.

A power tool has a body, a trigger, a motor, a shaft set, a ball screw, and a pre-fastening module. The pre-fastening module has a first pre-fastening detecting member and a second pre-fastening detecting member. The first pre-fastening detecting member is moved with a connecting shaft of the shaft set in an axial direction. The second pre-fastening detecting member is located on a moving path of the ball screw. When a threaded spindle of the shaft set is inserted in a rivet nut and the connecting shaft is pressed to move inward the body, the first pre-fastening detecting member is moved to align with the second pre-fastening detecting member, and the motor is started automatically to drive the threaded spindle to rotate relative to the rivet nut. The motor will be stopped automatically after the rivet nut is pre-fastened on the threaded spindle, and this is convenient in use.
