Mountz TBIH Break-Over Wrenches (Interchangeable Head)
The Mountz TBIH is a small torque wrench ideal for applications with limited space. Torque range suitable for micro, low, and medium torque applications.
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 the operator tampering with settings.
The TBIH 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.
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.
Head interchangeability is intended for use during recalibration to allow reconfiguring tools for different applications. They are not intended to be interchanged as a normal part of a manufacturing process.
If you need a break-over tool that is ESD safe or a higher torque range, see the Mountz TBX break-over wrench.
NOTE: Due to branding changes TBIH wrenches may be shipped with varying engraving designs during our update process. This change does not impact product functionality.

Description
The Mountz TBIH is an interchangeable head torque wrench with a break-over action, built for low-torque assembly in Singapore. One calibrated handle accepts TBIH open-end, box, ratchet and hex heads, so a line can cover several fastener sizes without buying several wrenches. Colour-coded handles make each preset value easy to identify.

Calibration & Service:
- Torque Analyzers & Sensors: If torque tools slip out of calibration, that could impact the quality of your products. An accurate way to regularly test calibration onsite is a great way to reduce risk and ensure safety. With Mountz torque analyzers and sensors, you can test tools before they go into service daily or weekly.
- Hex Step Adapters: When performing torque wrench calibration or testing, adapters are often needed, especially with torque wrenches with open-end heads. Mountz’s calibration hex step adapter features three or four common sizes, increasing the productivity of your torque wrench calibration process. This adapter will make testing and calibration efficient and straightforward.

Where the interchangeable head torque wrench fits in Singapore
Colour-coded TBIH handles are popular on electronics and medical device lines in Singapore, where several stations use different low torque values side by side. For instance, a red handle can mean one value and a blue handle another, so the wrong wrench is obvious at a glance. In addition, the break-over action stops over-tightening on small, delicate fasteners.
Pair it with
- TBIH wrench heads in open-end, box, ratchet and hex styles.
- TB fixed-head break-over wrenches where one fastener size is enough.
- Mountz torque analyzers to set and verify each handle.
Frequently asked questions about the interchangeable head torque wrench
Why choose an interchangeable head torque wrench
It lets one calibrated handle serve many fastener sizes. Therefore, you buy and maintain fewer wrenches and simply change the head for each job.
What do the handle colours mean
The colours carry no fixed value. Instead, your team assigns a colour to each preset torque so the right wrench is easy to pick at every station.
What torque range does the TBIH cover
Four bands cover 17.7 to 35.3, 33.9 to 135.6, 135.6 to 237.3 and 226 to 565 cN·m, suffixed A to D in the part number.
Does the break-over action prevent over-torque
Yes. When the set value is reached the head pivots and the operator feels the stop, so very little extra torque passes through.
