CDI Micro Adjustable Torque Screwdriver, 1/4 Inch Hex Drive, Range 5-40 In Lbs (401SM)

The CDI 401SM Micro Adjustable Torque Screwdriver is a precision torque control tool designed for applications that demand accurate and repeatable tightening — from electronics and instrumentation work to automotive and assembly tasks. Adjustable from 5 to 40 inch-pounds, this screwdriver lets you dial in just the right torque setting with a positive locking pull-down adjustment knob and a clear easy-read window scale. Its trilobular comfort grip reduces hand fatigue, and the universal 1/4″ hex bit holder with rare-earth magnet makes working with standard bits fast and secure. A cam-over torque limiting clutch helps prevent overtightening and potential damage to components, while automatic lock-in for counterclockwise rotation makes fastener removal just as effortless.
