INSIZE IST-41WM200 Interchangeable Head Preset Torque Wrench 40~200 N.m

The INSIZE IST-41WM200 is a preset torque wrench: INSIZE sets its torque value at the factory, within an adjustable range of 40~200 N.m (30~150lb.ft), so it cannot be knocked out of setting during use. Its interchangeable head takes an 18×14mm socket, accuracy is ±3%, 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 417mm long and the wrench weighs 860g, suited to production lines and workshops that repeatedly tighten the same fastener to one torque.
