The CAL 36/4 and CAL 40 Adjustable Torque Screwdrivers

The S/R CAL-Series Adjustable Torque Screwdrivers are ideal for any application where:

High repeatability for low torque is needed.
Excellent durability and versatility are needed.
These needs are common in high-precision operations such as electronics and electro-mechanical repair.

Bi-directional Accuracy of +/- 6% Indicated Value from 20% to 100% of capacity meets or exceeds ASME B107.300-2010 and ISO 6789.
Incredibly durable; many owners have experienced a service life of 10+ years!
Operator cannot overtorque. Clutch releases automatically when desired torque has been achieved.
Scale on shaft is marked in dual incrementation (in. lbs. and NM) on Cal 36/4, kgf•cm on CAL 40.
Magnifying lens improves view of clearly engraved scale.
To operatie, simply dial torque setting and insert bit.
Uses standard bits, adapters and sockets.
Anti-backlash design enhances repeatability.
Comes with FREE certificate of calibration from our ISO/IEC 17025 Accredited Calibration Laboratory. CAL 36/4 can be ordered with certification for English or SI units of measure.
