It doesn't require much force to over-torque miniature fasteners in critical applications for life-saving medical devices, aerospace instruments and micro electronic components. Designed for fastening applications where errors simply aren't acceptable, the FG-25z preset torque screwdriver applies the right amount of torque every time. Preset hand torque screwdrivers are ideal for fastening applications where operators repeatedly assemble parts at the same torque setting. Built with a cam-over design, the accurate screwdriver prevents a fastener or bolt from being under and over-tightened. As a quality control tool, the screwdriver allows any user to deliver the correct torque with confidence regardless of task and operator skill level. Using a quality torque screwdriver ensures that proper torque is being applied and maintains requirements associated with ISO quality standards. The mini FG preset screwdriver allows an engineer to ensure that the correct torque value is consistently applied to each miniature fastener and prevents costly over-torque events. Quality-minded engineers can give Mountz Mini FG tools to any operator and have the confidence that he/she will deliver the correct torque, time after time. With FG, you can Proceed with Confidence.

The torque screwdriver is pre-set to the required torque value of the application. A preset torque screwdriver does not feature an external adjustment scale. These tools have an internal adjustment mechanism for setting the torque value and must be preset internally using a hex key and a torque tester. However, if the torque specification changes or a new project requires a different torque setting, the preset torque screwdriver is still flexible enough that a new torque setting can be set internally using a torque analyzer.


  • 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 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 scaleā€”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).
