The Mountz TBIH is a small torque wrench ideal for applications with limited space. The flexible preset wrench can adapt to different fastening applications as it is compatible with varying head options like an open end, box end, flare end, hex key end, or a ratchet head. Preset torque wrench improves productivity by consistently applying the correct torque value to each fastener. The preset wrench is ideal for fastening applications where operators repeatedly assemble parts at the same torque setting. Torque wrenches require regular calibration to maintain accuracy and avoid errors in assembly processes. The Mount Loading Bench enables faster operator calibration by minimizing user-induced errors and transducer misalignment, ensuring reliable torque application every time.

Calibrating Break-Over-Over Wrench To calibrate break-over wrench, either use a torque analyzer or torque sensor within the torque wrench range. For break-over wrenches, calibrate torque in "Peak" mode with a torque tester or torque sensor. Make sure to apply the torque slowly and smoothly. 1. Select a torque tester or torque sensor that covers the torque range of the wrench. Connect the wrench to the torque tester or sensor and use the appropriate adapters. 2. Apply torque clockwise slowly until wrench 'breaks-over' and note reading. 3. Adjust wrench to required torque setting as described above. 4. Test and repeat adjustment as necessary to obtain desired torque value. 5. Recalibrate break-over wrench at prescribed intervals.

Maintenance Schedule Like an automobile, torque wrenches contain moving parts that require periodic servicing and lubrication.
Period Between Resetting of Torque 5,000 fastening operations. It is acknowledged that some tools may achieve 5,000 operations in a relatively short period of time. Under these circumstances, the user may decide, with the benefit of their experience, to increase the period between calibration intervals. Testing and Servicing Torque tools go out of calibration with use. Calibrating a torque tool is a fine-tuning process of bringing the tool back within its tolerance. Regular torque calibration of a break-over wrench ensures accuracy, repeatable tool performance, and adherence to international standards. We recommend a general once a year calibration interval. However, the user's Mountz Service Locations
