INSIZE IST-41WM800 Interchangeable Head Preset Torque Wrench 160~800 N.m

The INSIZE IST-41WM800 is a preset torque wrench: INSIZE sets its torque value at the factory, within an adjustable range of 160~800 N.m (120~600lb.ft), so it cannot be knocked out of setting during use. Its interchangeable head takes a 32×24mm socket, accuracy is ±3%(≤500N.m)/±4%(>500N.m), and it works clockwise only. Owners can reset the value themselves with INSIZE's optional torque adjustment tool or an IST-TT digital torque tester, rather than dialling a fresh value in before every job. The metal handle is 1030mm long and the wrench weighs 4.8kg, suited to production lines and workshops that repeatedly tighten the same fastener to one torque.
