The MP2454 Direct Drive Pneumatic Screwdriver is a quality tool manufactured by Master Power, a division of Apex Tool Group. The "stall drive" air controlled screwdriver has a two-step throttle, which offers operator control over torque applied. The direct drive or "stall drive" of the MP2454 rotates the fastener until resistance overcomes motor power and the motor stalls. Torque output on the Master Power air screwdriver is set by adjusting the air pressure. With high parts interchangeability, Master Power tools can be easily repaired, keeping tool costs down.

Master Power air screwdrivers are rated in terms of "free speed" (the RPM of the drive spindle with no load at recommended air pressure and the throttle wide open). Use a calibrated torque wrench to check torque on the job. Select proper tool speed for your pneumatic air screwdriver so that stall torque is greater than, or at least equal to, the torque required for the largest screw or bolt and nut on which the screwdriver will be used. While pneumatic screwdrivers with lower RPM provide higher torque and more closely controlled torque, they increase run-down time. If run-down time is an important cost factor, a compromise between accuracy and speed must be reached.
