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. A simple, cam-over
design prevents over-tightening and possible
damage to components.
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!
Positive locking knob makes accidental setting
changes impossible. Automatic lock in
counterclockwise direction makes fastener
removal a snap. The Micro-Adjustable series
includes six models with torque settings ranging
from 20 in. ozs. to 40 in. lbs.

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.
The Pre-Set series includes four models
with available torque settings from 6 in. ozs.
up to 40 in.lbs. When precision and
repeatability are a must, the choice is
simple - CDI Torque Screwdrivers.
