Catalog Link (PDF):  [Page 21]  


Pre-Set Torque Screwdrivers

 The tamper resistant design of the Pre-Set series is particularly suited for high-volume use in assembly operations. A simple, cam-over design prevents over-tightening and possible damage to components.

Pre-set Screwdrivers may be ordered factory set at no additional charge or they may be easily set with any quality torque calibration system. The end cap removes for easy access to the 1/8” hex adjustment screw. A hex adjustment key is included with each driver.

Micro-Adjustable Torque Screwdrivers

 Adjustable models offer versatility for applications that require more than one torque value. These torque screwdrivers are particularly suited for the electronics industry and for instrument assembly work.

Torque settings are easily and accurately changed with a unique adjusting knob and easy-to-read window scale. Adjusting the screwdriver is simple. Just pull out the adjusting knob to unlock, turn to the desired setting, then push the knob in until it clicks!
