This wrench is designed and manufactured to meet or exceed the accuracy and repeatability requirements of ISO 6789:2003 ( 6% of setting).

• Small and lightweight
• Tamper-proof internal adjustment
• Ideal for use in restricted spaces

Breaks-over when preset torque is reached eliminating overtorquing. The break-over mechanism minimizes shock to assemblies. No external adjustment scale must be preset using a torque analyzer. When the TB wrench achieves torque, the head breaks-over preventing the operator from overtorquing the fastener. Interchangeable heads are manufactured with a common center line
so the torque setting remains the same when head sizes are changed.
