Quality cam-over technology in the palm of your hand for cleanroom environment THE STATE-OF-THE-ART PRECISION TORQUE DRIVER Engineered and assembled in Silicon Valley, the Mountz FG line of precision preset cleanroom torque screwdrivers are the most advanced hand tools for high-level process and quality control. The screwdriver’s repeatability, traceability, and precision safeguards against fastening failures. Designed for a cleanroom environment, the Mountz screwdriver is manufactured using a high-grade, low-outgassing powder coat. The tools feature dynamic wear-resistant internal seals to prevent grease leakage and minimize airborne contamination. 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 the 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 The Mountz FG cleanroom screwdriver calibration life exceeds the stringent industry standard (ISO 6789). The FG is an error-proofing tool that allows engineers to reduce quality risks
for critical fastening applications with a torque range suitable for micro, low, and medium torque applications. The cam-over technology applies the correct torque and prevents over-torque events. 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 the consistency of torque delivered and joint reliability.

Cleanroom Torque Screwdrivers Manufacturing electronics, semiconductors, biotech, and medical devices demand care and precision. Often, a controlled environment is needed during production to limit the amount of dust, particles, and other contaminants in the manufacturing area. A cleanroom environment controls the level of contamination. Eliminating any sub-micron airborne contamination is a controlled process. Cleanrooms are used in many industries where small particles can adversely affect the manufacturing process. With the demand for cleanroom manufacturing increasing, the need for torque tools that meet stringent cleanliness requirements has increased. Responding to this industry need, Mountz offers a selection of cleanroom torque screwdrivers.
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 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 is ready to be used. However, if the preset torque value needs to be changed for a new fastening application, the flexible tool can easily be adjusted to a new preset torque value.
