MTBN Break-Over Wrench

MTBN Break-Over Torque Wrench
Click images to enlarge.
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.

Features

  • A preset production torque wrench with flexibility to adapt to different applications with ability to change different head options. Breaks over upon reaching preset torque and reset automatically.
  • Tamper-proof internal adjustment. No external adjustment scale - must be preset using a torque analyzer.
  • All models are are fitted with “double positive” torque adjustment locking system to prevent tampering.
  • Compact and well balanced. Ideal for use in restricted areas.
  • Interchangeable Heads for all models are available.
  • MTBN2 & MTBN10 are ESD compliant.
