Break-Over Torque Wrench with Fixed Head | Checkline TB

Category:

The TB is a small torque wrench with a fixed head. The versatile preset wrench is available with different head configuration options, like open end, box end, flare end, hex key end or ratchet head. TB models are designed to have one permanent head style attached to it. When the TB torque wrench achieves torque, the head breaks-over signaling to the operator to stop applying torque to the fastener or bolt. Break-over torque wrenches improve control of the fastening process by reducing the risk of both over and under tightening.

Note! The TB wrench comes with head permantely attached to it. It is not removable. The TBIH wrench allows you to remove the wrench head and add another option.
