A blind rivet nut-setting tool for setting a rivet nut including a housing having an anvil, a pull stud for engaging the rivet nut, and an output shaft defining a drive axis. The tool includes a motor defining a motor axis. The motor is configured to transfer torque to the output shaft to rotate the pull stud about the drive axis. The tool includes a clutch mechanism that is disposed between the motor and the output shaft. The clutch mechanism is moveable between an engaged state, in which a reaction torque exerted on the pull stud is below a predefined torque threshold, and a disengaged state, in which a reaction torque exerted on the pull stud is equal to or above a predefined torque threshold. The tool includes a pull mechanism that is driven by the motor and capable of translating the pull stud along the drive axis.
