Engineered and assembled in Silicon Valley, the Mountz TBX line of precision preset break-over wrenches ensures consistent process and quality control by providing operators with a break-over wrench that helps you support your quality control inspectors by empowering your workers to prevent assembly errors. Torque range suitable for low to higher torque applications. Designed to tighten diverse fasteners accurately, break-over wrenches inform their operator when the right torque is reached by deflecting on their built-in hinge. As a result, you can reduce defective products and rework related to over- and under-torque conditions. Their small size enables them to fit into areas with tight clearances, boosting productivity and project ROI. With interchangeable heads, Mountz break-over wrenches allow you to switch out heads for tricky fasteners and to get more use out of your existing tools. NOTE: Head interchangeability is intended for use during recalibration to allow reconfiguring tools for different applications. They are not intended to be interchanged as a regular part of a manufacturing process. TBX break-over wrenches have a calibration life of 4x ISO standards that is unmatched by any click wrench on the market to keep your tools out of the lab and on the production floor.

Reliable break-over technology in the palm of your hand QUALITY TORQUE WRENCH DELIVERS CONFIDENCE AT EVERY TURN Engineered and assembled in Silicon Valley, the Mountz TBX line of precision preset break-over wrenches ensures consistent pro- cess 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 break-over wrenches help support your quality control process by empowering an operator to prevent assembly errors. Designed to tighten various types of fasteners accurately, the break-over wrench informs the operator when the proper torque is reached by deflecting at the pivot point near the tool's end. The unique break-over mechanism gives an operator ample time to react once the target torque is achieved and stop applying additional force to the fastener. Our break-over technology increases the consistency of torque delivered and joint reliability. Execute fastening tasks with precision and repeatability Mountz TBX tools stay in calibration 4X longer than the most stringent industry standard (ISO 6789). The torque limiting wrench is engineered with a break-
over mechanism that enables manufacturers to achieve and main- tain process reliability. You can give Mountz TBX wrenches to any operator and have the confidence that he/she will deliver the correct torque, time after time.

Preset break-over torque wrench improves productivity Modern, effective preset torque wrenches improve productivity by consistently applying the correct torque value to each fastener. Preset break-over wrenches are ideal for fastening applications where operators repeat- edly 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 breaks over, pro - viding a visual indicator 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 a new fastening application, the flexible tool can easily be adjusted to a new preset torque value.
