Norbar NorTorque® 340 Adjustable Dual Scale Ratchet Torque Wrench 1/2in Drive 60-340Nm

The Norbar NorTorque® 340 is an adjustable dual scale ratchet torque wrench built on Norbar's proven mechanism and internal components, offering professional-grade accuracy in a purposeful, value-for-money package. With a 1/2in square drive and a working range of 60-340Nm (50-250 lbf·ft), it covers the top end of the NorTorque range, suited to heavier mechanical and automotive fastening tasks. Accurate to ±3%, meeting the requirements of ISO 6789-1:2017, and supplied with a Declaration of Conformance. Part of the full Norbar range at MTN Shop UK.

A push-through ratchet with 60 teeth allows operation in both clockwise and counter-clockwise directions, while a narrow engagement angle lets the wrench be positioned easily in confined spaces. The secure push/pull locking mechanism is quick and intuitive to use, preventing accidental adjustment once the torque is set, and a micrometer scale on the robust single-material handle makes setting fast and error-free. A convenient hanger feature aids storage as well as wrench unlocking and adjustment, and the handle centre is clearly marked for calibration reference.

Frequently Asked Questions

What jobs need a 60-340Nm torque wrench instead of a smaller one?
A 60-340Nm range, like the Norbar NorTorque 340, suits heavier fastening tasks than typical wheel nuts or engine ancillaries, such as suspension arms, commercial vehicle components, and larger structural bolting. If your work mostly involves lighter automotive fasteners under 100Nm, a smaller model like the NorTorque 100 will give better accuracy in the middle of its range for those jobs.
How do I set the torque on the NorTorque 340?
Rotate the handle to align your target value on the dual Nm/lbf·ft scale, then use the push/pull locking collar to lock the setting in place so it doesn't shift during use. Tighten the fastener steadily until you feel and hear a distinct click, which signals the set torque has been reached; stop applying force at that point rather than continuing to turn.
Why does accuracy matter most in the middle of a torque wrench's range?
Torque wrenches, including the NorTorque 340, are calibrated and most accurate around the middle third of their stated range. Using a wrench near the very bottom or top of its range increases the chance of reduced accuracy, so if most of your work sits near 340Nm, it may be worth checking whether a higher-range Norbar model is a better fit than pushing this wrench to its upper limit.
Can the NorTorque 340 be used to loosen bolts as well as tighten them?
Yes. The push-through ratchet allows the direction to be switched between clockwise and counter-clockwise, so the same tool can be used to loosen fasteners as an ordinary ratchet. Torque measurement only applies in the tightening direction.
How often should this torque wrench be recalibrated?
Norbar recommends calibration checks roughly once a year or after a set number of uses, whichever comes first, since mechanical torque wrenches can drift out of tolerance with heavy use. The NorTorque 340 is supplied with a Declaration of Conformance confirming its accuracy at the time of manufacture, and Norbar offers ongoing calibration services.
