Norbar manufactures precision torque tool and torque calibration equipment and, with branches in UK, USA, Australia, New Zealand, Singapore and China plus worldwide distributor coverage, can serve industry globally.

Norbar has developed an expertise in serving offshore technology industries, particularly in sub-sea tools and measurement systems to be operated from ROVs and torque equipment for harsh environments.


Norbar offer a huge range of hand operated torque wrenches covering torque values from 1N.m to 1,500N.m.

The range includes models with robust, square drive ratchet heads and models with a spigot to accept a range of interchangeable fittings. This versatility means that torque control can be brought to most bolts.

Using the USM instrument, bolt load can be precisely calculated during tightening and monitored over time.
Norbar's torque wrenches are complemented by our Handtorque™ range of torque multipliers.
Pneutorque® pneumatic wrenches provide smooth continuous torque with low noise, low vibration and high accuracy. They are used for bolting and non-bolting applications such as valve actuation.
Norbar manufactures a wide range of torque calibration products from simple, low cost torque wrench testers through to calibration masters for torque calibration laboratories.
Norbar specialises in developing ‘specials’ for subsea/harsh environments; contact us about our ‘engineered to order’ capabilities.

Norbar’s robust and unique ‘Industrial’ torque wrench features a 20 degree break angle. This cam controlled mechanism ‘breaks’ gently so that the operator is always in control. The major advantage of this system is that it virtually eliminates over torque.


To apply greater torques with a hand torque wrench either means increasing the lever length or increasing the force applied. Both of these can be impractical or dangerous. For higher torques Norbar have developed a range of torque multipliers which, in combination with a torque wrench, can apply very high torque with great accuracy in a compact package. For example, 1,000N.m can be safely and accurately applied with a total package weight of 2.85kg and a lever length of 307mm.

The above example is Norbar’s smallest torque multiplier. Other models are available to apply torques up to 100,000N.m.

Handtorque™ multipliers can be powered with a hydraulic motor. Many such multipliers are used sub-sea, operated from ROVs.

Reducing mass on ROVs is critical and Norbar have experience in the use of light weight materials to make substantial weight reductions when compared with our standard products in order to meet the needs of our customers.


When a powered bolting solution is needed for high torque fasteners, the Pneutorque® offers unmatched performance in many key respects. It offers accurate torque control, it is quiet (less than 85dB), vibration is virtually negligible (approximately 1m/s²) and the tools are fast compared with ratcheting hydraulic torque wrenches.

The Pneutorque range covers torques from 100N.m to 100,000 N.m. They are not just for bolting but can be used for any application where a high, continuous torque output is required such as value actuation, barring of engines or other heavy equipment during build or maintenance and cable tensioning.


Norbar’s range starts with the simple to use and low cost ‘TruCheck’ torque wrench tester and extends through to full torque calibration laboratories.

Our ‘Harsh Environment’ (HE) range has been designed specifically with the needs of the offshore industry in mind. The heart of the system is the HE display instrument which is IP65/67 rated. To complement the instrument, a range of HE transducers is available, fully manufactured in stainless steel and sealed against water and dust ingress. Transducers for sub-sea use can be engineered for the particular applications of ROV operators.


Norbar have set up calibration laboratories for torque up to 6,800N.m and accredited to national standards in the United Kingdom (UKAS), Australia (NATA), USA (NVLAP) and Singapore (SINGLAS). The UK factory also offers calibration traceable to national standards up to 100,000 N.m. Through our own facilities and those of our distributors, we can support our products worldwide.


Using ultrasound, Norbar’s USM can measure the change in length of a bolt due to the tightening process and from this the precise load in the bolt can be calculated by the instrument. Ideal for critical fasteners, this system can determine the load in a bolt many times more accurately than torque control alone.
