Norbar Torque Wrenches

Norbar tools are world-renowned for their accuracy and robust build quality; HK Calibrations supplies these wrenches because they provide consistent, repeatable torque control that is essential for safety-critical applications in the mining, aviation, and transport sectors.

Most Norbar professional series wrenches boast an accuracy of +/-3%, which exceeds the international standard of +/-4%; HK Calibrations ensures these precision instruments help you mitigate variables like friction and operator error for perfect bolt tension every time.

To maintain peak performance and safety, HK Calibrations and the manufacturer recommend calibration every 12 months or every 5,000 cycles—whichever comes first—especially when used in high-volume production or heavy industrial environments.

While many traditional wrenches require being "relaxed" to the minimum setting, Norbar’s high-quality spring materials are designed to resist fatigue; however, HK Calibrations specialists still suggest winding back to the minimum scale marking (not zero) as a best practice for long-term storage.

Any mechanical shock can alter the internal settings of a precision instrument; HK Calibrations strongly advises having the tool checked and recalibrated immediately if it is dropped to ensure it hasn't drifted out of its specified tolerance.
