Quality cam-over technology in the palm of
your hand
PRECISION TORQUE WRENCH DELIVERS CONFIDENCE AT EVERY TURN
Engineered and assembled in Silicon Valley, the Mountz FGC line
of precision preset cam-over wrenches are the most advanced
torque wrenches for high-level process and quality control. The
wrench’s repeatability, traceability, and precision safeguards
against fastening failures.
When under- or over-torquing puts your products at risk, Mountz
cam-over wrenches deliver the accuracy you need. Mountz
cam-over wrenches use an internal cam-over mechanism to
reduce the risk of operator error by disengaging once torque is
reached. Our cam-over technology increases consistency of torque
delivered and joint reliability.
Precision and accuracy delivered every time
Mountz FGC tools stay in calibration 2X longer than the most
stringent industry standard (ISO 6789). Engineered with a
cam-over mechanism, the poka-yoke wrench
prevents over torque. Implementing this errorproofing wrench removes the operator
influence out of the torque equation
and delivers an accurate and
repeatable fastening result
than a standard click type
wrench. You can give
Mountz FGC wrenches
to any operator and have
the confidence that he/
she will deliver the correct
torque, time after time.

Preset cam-over torque wrench
improves productivity
Modern, effective preset torque wrenches
improve productivity by guaranteeing that
the correct torque value is consistently applied
to each fastener. Preset cam-over wrenches are
ideal for fastening applications where operators
repeatedly assemble parts at the same torque
setting. A preset wrench is similar to setting
an alarm clock to signal the achievement of a
selected time. The wrench is pre-set to the
application’s required torque value. The tool
signals once torque is achieved.
A preset wrench doesn’t have an external torque
adjustment scale. These tools have an internal
torque adjustment mechanism for setting the
torque value and preset using a hex key and
a torque analyzer. The locking mechanism
prevents accidental torque setting changes.
Once the tool is set the wrench’s end cap is
sealed with a calibration sticker and ready to be
used. However, if the preset torque value needs
to be changed for new fastening application
the flexible tool can easily be adjusted to a new
preset torque value.

The stamp for quality tools
Mountz FGC wrenches comply with
ISO6789 and are constructed from high
quality materials, engineered for superior
reliability and safety and backed by an
industry leading warranty. Look for the
Mountz hexagon logo – it’s a stamp for
quality tools, service and knowledge in
the field of torque control.
It’s why we have an industry-leading
warranty.
• Mountz FGC tools are the only cam-over
wrenches on the market to offer a twoyear unlimited warranty. If it breaks in
any way, we’ll fix it or replace it for free.
• Lifetime guarantee against
manufacturing defects.
• Warranty includes a free calibration
within the first year.
