Engineered and assembled in Silicon Valley, Mountz Torque FG preset precision torque screwdrivers are the most advanced hand tools in the world. Torque range suitable for micro, low, and medium torque applications. Preset torque screwdrivers improve productivity by consistently applying the correct torque value to each fastener. They are ideal for fastening applications where operators repeatedly assemble parts at the same torque setting. A preset screwdriver 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. Designed for industries where production errors aren't acceptable, poka-yoke torque screwdrivers prevent over-torque events. Quality-minded engineers can give Mountz FG tools to any operator and have the confidence that they will deliver the correct torque, time after time.

Quality cam-over technology in the palm of your hand THE STATE-OF-THE-ART PRECISION TORQUE DRIVER Engineered and assembled in Silicon Valley, the Mountz FG line of precision preset torque screwdrivers are the most advanced hand tools for high-level process and quality control. When under- or over-torquing puts your products at risk, Mountz cam-over torque screwdrivers deliver the accuracy you need. Mountz cam-over drivers 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 BREAKTHROUGH ACCURACY AND REPEATABILITY INCREASES OPERATOR CONFIDENCE AND OVERALL QUALITY OF ASSEMBLY Mountz FG tools stay in calibration 4X longer than the most stringent industry standard (ISO 6789). Engineered with a cam-over mechanism, the poka-yoke screwdriver prevents over torque. You can give Mountz FG tools to any operator and have the confidence that they will deliver the correct torque, time after time. Our unique bearing
system eliminates axial (end) and side loads by the operator, increasing consistency of torque delivered and joint reliability.

Preset cam-over torque screwdriver improves productivity Modern, effective preset torque screwdrivers improve productivity by guaranteeing that the correct torque value is consistently applied to each fastener. Preset torque screwdrivers are ideal for fastening applications where operators repeatedly assemble parts at the same torque setting. A preset screwdriver is similar to setting an alarm clock to signal the achievement of a selected time. The screwdriver is pre-set to the application’s required torque value. The tool signals once torque is achieved. A preset screwdriver 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 screwdriver’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 last precision torque screwdriver you’ll ever need to buy! We’ve tested them over millions of cycles in our controlled lab environment and we still can’t break them! It’s why we have an industry-leading warranty. • Mountz FG tools are the only cam-over drivers on the market to offer a two year 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.

FG-OWC (ONE WAY-CLUTCH) A one-way torque clutch system is designed to apply torque in one direction and remains positive (no torque control) in the opposite direction. This allows the tool to be used for easy screw removal. Ideal for maintenance and refurbishing applications and where undoing or loosening screws is required. Screwdriver is torque limiting and calibrated in the CW direction only Designed and manufactured to meet or exceed the accuracy and repeatability requirements of ISO 6789: 2017 (+/- 6% of setting). Color coding labels allows for torque setting identification in manufacturing area.
**A removable, sliding T-bar is supplied with FG-40i OWC and FG-125i OWC models.
Tamper-proof internal adjustment. No external adjustment scale—must be preset using a torque analyzer.

FG-IFR (IMPACT FREE RESETTING) The FG screwdrivers’ design action is such that when the tool reaches its pre-set torque value, the mechanism disengages from the drive, limiting the torque. Further rotation of the screwdriver handle resets the mechanism, ready for the next torquing operation. The FG-IFR models eliminate any slight reaction during resetting. Designed and manufactured to meet or exceed the accuracy and repeatability requirements of ISO 6789: 2017 (+/- 6% of setting). Color coding labels allows for torque setting identification in manufacturing area.
***A removable, sliding T-bar is supplied with FG-40i and FG-125i IFR models.
