TB 斷裂扳手

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.

Their small size enables them to fit into areas with tight clearances, boosting productivity and project ROI.

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 4 – 5 weeks. For further information, submit a contact us form, call or send us a web chat.

The TB wrench comes with a head permanently attached to it. It is not removable.

NOTE: Due to branding changes TB wrenches may be shipped with varying engraving designs during our update process. This change does not impact product functionality.
