Reduce the Risk of Bolting Failures with a Break-Over Torque Wrench
Break-over wrenches improve control of the bolting process by reducing the risk of both over and under-tightening. Upon reaching the preset torque value, the tool "breaks" at a specific point along the tool's shaft — usually at a pivot point near the tool's head. 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.
The MTBN break-over wrench is a preset production torque wrench with flexibility to change to a different head option once a long-term production project is finished or modified. A preset torque wrench is similar to a person setting an alarm clock to signal the achievement of a selected time. The torque wrench is pre-set to the required torque value of the application and then the tool signals the operator when torque is achieved.
The compact and well-balanced MTBN features a tamper-proof internal torque adjustment setting. There is no external adjustment scale, so the wrench must be preset using a torque tester. Designed and manufactured to meet or exceed the accuracy and repeatability requirements of ISO6789: 2003, Mountz offers various MTBN wrench models covering a torque range of 1.8 inch-pounds up to 147 foot-pounds.
Using a quality torque wrench makes a safer world through accuracy and precision. Controlling torque is essential for companies to ensure their product's quality, safety and reliability isn't compromised. The failure of a three-cent fastener that isn't properly tightened can lead to catastrophic or latent failures. Fasteners that are insufficiently fastened can vibrate loose and excessive torque can strip threaded fasteners.
