Frequently Asked Questions
General Questions
What is torque?
Torque is any force or system of forces that tends to cause rotation about an axis.
It is often represented by the symbol “τ” (tau) and is measured in units such as newton-meters (Nm) or foot-pounds (lb-ft) in the International System of Units (SI) or the imperial system, respectively.
Why is lubrication important?
Lubrication is crucial in torque applications to:
- Reduce Friction: Minimises resistance, improving efficiency.
- Prevent Wear: Protects moving parts from abrasion, extending component lifespan.
- Control Temperature: Dissipates heat generated by friction, preventing damage.
- Protect Against Corrosion: Maintains metal surfaces, reducing surface roughness.
- Ensure Seal Effectiveness: Aids in preserving seals and preventing contamination.
- Reduce Noise: Dampens vibrations, minimising undesirable sounds.
In essence, proper lubrication is essential for minimising friction, wear, and heat, while maximising the efficiency and longevity of torque systems.
Can I buy direct from you?
Do you stock a RAD gun?
Well, yes and no. Fun fact is that it’s actually called a powered multiplier and while we do not stock the RAD version of it, we do stock the Norbar equivalent range PTS and EBT. We’ve been told ours is quieter, more robust, has less gearbox failures and is cheaper to service and repair. You be the judge.
Do you have tools for hire?
Yes we do. Simply email us at norbar@norbar.com.au or call +61 (08) 8292 9777 and let us know what you’re after.
Why is accuracy so important?
Precision is paramount, and Norbar takes the lead in providing the market’s most accurate torque wrenches. With a remarkable 25% improvement over the industry standard, our professional series boasts an accuracy level of +/-3%, surpassing the typical +/-4% found in hand wrenches and most torque tools. The significance of accuracy cannot be overstated, considering the multitude of factors influencing bolt load—such as the condition of the nut and bolt, lubrication, temperature variations, operator error, and parasitic forces. Utilizing an accurate torque wrench becomes a critical factor in mitigating these variables.
Products
What is the best hand torque wrench in the market?
The Small Professional series. Since its original, award winning launch in 1984, Norbar’s Professional torque wrench range has become one of the most popular wrench ranges available worldwide. In this re-engineered version, the core principles of accuracy, durability and comfort are carried over but almost every component part is new and improved.
Do you have powered multipliers in your range?
Yes, we do have several powered multipliers to suit different applications. You can view our whole range of powered multipliers here.
Want an entry-level torque wrench but too many to choose from?
Look no further than our Nortorque range: Accurate to +/-4% , reliable, easy to service, and spare parts are available!
The NorTorque wrenches come with features such as an adjustable dual-scale, allowing users to set torque values precisely. For example, the NorTorque model 340 is a 1/2″ torque wrench with an adjustable ratchet and dual-scale, providing flexibility in torque applications

Calibration, Service & Repairs
How often should I have my Torque Wrench recalibrated?
To ensure peak performance, it is advisable to calibrate and service your torque wrench in accordance with the original equipment manufacturer’s (OEM) specifications. As a general guideline, we recommend scheduling calibration every 12 months. At Norbar, you have the option to conveniently send your torque wrench to one of our five branches for calibration services. Alternatively, we are available to guide you towards the appropriate resources for on-site calibration.
How often should I have my Torque Multiplier recalibrated?
The standard recommendation is that customers recalibrate their Torque Multiplier at least once a year (or 5,000 cycles), and more frequently if used for critical fasteners.
What is NTS?
NTS is short for Norbar Technical Services, and forms part of Norbar’s service to its customers, consisting of a team of onsite service & support technicians available through our Norbar network.
How does regular scheduled maintenance and servicing help save me money?
Do you do NATA-certified calibrations?
Yes, we do. In fact, we’re one of only a few NATA approved facilities in the country.
Why do I need NATA certification?
Can my NATA calibration be completed on the same day?
Can you calibrate other brand wrenches?
What standards are used to complete the NATA calibrations?
Do you need to order parts in before you can conduct repairs? How long will that take?
