*Calibration life is 4x ISO standard for FG-8i, FG-20i, FG40i and FG125i models only. A removable, sliding T-bar is supplied with FG-40i and 125i models.
    • Torque screwdriver prevents operators from influencing the torque output when tightening fasteners.
    • Accuracy and precision delivered for all fastening applications.
    • Engineered with a cam-over mechanism, the poka-yoke screwdriver prevents over torque.
    • Advanced cam-over technology provides a completely smooth reset reducing the risk of users loosening fasteners or breakage.
    • *Calibration life is 4x ISO standard for FG-8i, FG-20i, FG40i and FG125i models only.
    • Calibration life is 2x ISO standard for FG-25z models only.
    • Unique bearing system eliminates axial load and side load on the fastener applied by the operator.
    • Unmatched security of the tamper-proof internal adjustment. No external adjustment scale—must be preset using a torque analyzer.
    • Patented secure bit locking mechanism with one-touch release can only be activated by the user for greater flexibility of applications and efficiency on the line.
    • Reduced bit wear lowers the incidence of bits falling out, which can slow production or cause product damage.
    • All models provide bi-directional operation and are calibrated in either the CW or CCW direction.
    • Ergonomic handles are designed with fewer flutes and larger recesses to make the tools easier to hold, less likely to cause hand fatigue, and makes drivers easier to clean.
    • Enable quick and error-free tool and torque setting identification with four different color-coding label options.
    • Two year unlimited warranty.
    • Lifetime guarantee against manufacturing defects.
    • New design improves serviceability, reduces downtime, and enables replacement of individual parts to extend the life of your investment.
    • Mountz extensive Cmk testing happened over 20,000 continuous torque readings and is documented in a Mountz-authored technical whitepaper.

The preferred and certified ranges of these tools is in accordance with the requirements of ISO 6789 (+/- 6% of indicated setting).
