The Britool HVT5000 is a classic torque wrench from a name you can trust. 3/4” in size with a torque range of 140-560Nm. This wrench works to an accuracy of +/- 4% and features a retractable adjustment mechanism for avoiding accidental adjustment. Also features a length independent mechanism and push through reversible mechanism. Unlike most other torque wrenches, the mechanism pivots around the square drive. This gives the major advantage in that the torque wrench is not length dependant. As a result there is no variation to the application of the preset torque value, no matter where the handle is grasped.
