DISCONTINUED ITEM
The 8400 series is designed for the customer who desires a less expensive torque screwdriver but still demands a clutch with an overall accuracy of 5%. The 8400 series is a lever operated tool in which, once torque value is reached, the clutch makes a chattering or ratcheting sound. The lever forward/reverse allows the operator a simple left-right movement to change directions simply and easily. The 8400 series is perfect for the customer who requires a higher torque tool but does not need the expense of an auto shut-off. Customers requiring an inexpensive pneumatic screwdriver with a torque range of 5 to 40 in lbs (0.55 to 4.5Nm) will appreciate the quality of this U.S. built tool.

The 8400 series uses part number 5980-5982 (see graphics to left.) clutch which can be set at the factory if requested. Any clutch or tool which is set at the factory will receive a certificate of calibration sheet which is N.I.S.T. traceable.
