Mountz TB Break-Over Torque Wrench

Preset Break-Over Torque Wrench w Fixed Head (selectable)

The Mountz TB is a small torque wrench ideal for applications with limited space. TB wrenches are designed to have one permanently attached head style. Torque range suitable for micro, low, and medium torque applications. 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 wrenches are ideal for fastening applications where operators repeatedly assemble parts at the same torque setting and ensure that the correct torque value is consistently applied to each fastener by reducing the risk of setting tampering by operators.

The TB wrench breaks over once it achieves its preset torque setting, signaling the operator to stop applying torque to the fastener or bolt. The wrench improves the fastening process by reducing either over or under-tightening risk.

TB Wrenches are made to order and typically ship within 6~7 weeks. The TB wrench comes with a head permanently attached to it. It is not removable. The small wrench size enables them to fit into areas with tight clearances, boosting productivity and project ROI.

Features & Benefits

• The preset wrench ensures that the correct torque value is consistently applied to each fastener. Designed to have fixed head permanently attached.
• Breaks-over 90° upon reaching preset torque. The break-over mechanism minimizes shock to assemblies.
• Improves the fastening process by reducing the risk of both over and under-tightening.
• Delivers repeatability, traceability, and precision for all tightening applications.
• Six different coloured aluminum handles allow for color-coding of specific torque values in production areas.
• Handle: 5” Length x 9/16” Diameter.
• No external adjustment scale – must be preset using a torque analyzer.
• Meets or exceeds the accuracy and repeatability requirements of ISO 6789:2017 (± 6% of setting).

Options (w costs)

• Preset value in required torque unit
• Calibration certificate
