Master Power 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 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. If you do not see a particular Master Power tool in the web store, call Customer Service at 1-800-476-6677. Any Master Power tool can be special ordered.

The MP2433 is a Versa Clutch screwdriver. The Versa Clutch on a pneumatic screwdriver allows the operator to externally adjust the engagement of the clutch plates providing a full range of torque. The Master Power Versa Clutch screwdriver is the best "all-purpose screwdriver for all trades." When the desired torque is reached, the operator can push and re-engage the clutch jaws in order to obtain more torque.
