MTBN Break-Over Wrenches

The MTBN is a preset production torque wrench with flexibility to adapt to different fastening applications as it is compatible with different head options. The unique break-over mechanism, provides an operator ample time to react once the target torque is reached and to stop applying any additional force to the fastener. Break-over torque wrenches improve control of the fastening process by reducing the risk of both over and under tightening.


MTBN 25, 65, 135 models operate in single direction (clockwise).
