A power tool includes a housing, a motor disposed in the housing, a motor controller disposed in the housing and electrically coupled to the motor, and a transmission disposed in the housing and coupled to the motor. A tool bit holder is rotatably driven by the motor via the transmission and receives a tool bit for rotatably driving threaded fasteners. A power switch and an electronic model select switch are actuatable from outside the housing and are coupled to the motor controller. The power switch controls power delivery to the motor. The electronic mode select switch is configured to select between at least a first mode of operation in which power delivery to the motor is controlled by actuation of the power switch and an electronic lock on mode in which continuous power is delivered to the motor upon a single actuation and release of the power switch.

A magazine is configured to be removably coupled to a power tool housing of a power tool. The magazine has a housing configured to be rotatably attachable to the power tool housing. An advancing mechanism is received in the magazine housing, and is configured to advance a strip of collated fasteners into position to be driven by the power tool. An indexing ring has a plurality of recesses and is configured to be non-rotatably attached to the power tool housing. A detent is biased to removably engage one of the plurality of recesses, and is configured to be non-rotatably attached to the magazine housing. The detent removably engages the recesses to allow for indexed tool-free rotation of the magazine housing relative to the power tool housing.
