The Professional torque wrench offers an ideal combination of accuracy, robust construction, comfort and ease of use. The push-through ratchets on these models are robustly engineered for strength and durability. The strength and high wear resistance comes from a coarse tooth pattern while a principle of offset ratchet pawls gives a narrow engagement angle. The push-through square drive is not only a robust design but allows the wrench to be used for torque control in both the clockwise and anti clockwise directions, and allows for a wider model range of up to 400 N·m.
*Accuracy of +/-3% of reading exceeds all international standards for torque wrenches.
*Every wrench is supplied with a calibration certificate to satisfy the requirements of ISO 9000.
*Soft feel handle provides excellent grip even in oily conditions.
*Handle materials and lens resist all chemicals in common automotive, industrial and aviation use.
*Locking mechanism prevents accidental adjustment of the wrench during operation.
*Retained square drive will not pull out of the head when the socket is removed.
*Supplied in moulded box for storage and protection.
*Long scale graduated in N·m and lbf·ft allows for foolproof and accurate setting. Kgf·m and lbf·in scales are also available.

Norbar is the world's leading torque specialist with one of the most modern and largest factories devoted exclusively to the design, development and production of torque tightening and measuring equipment.
Norbar is the only torque equipment manufacturer to be able to offer torque tool and instrument calibration & recalibration services to the original factory standard on four continents. The NATA accredited laboratory in Adelaide, South Australia and NVLAP accredited laboratory in Willoughby, Ohio, USA use the same equipment and procedures as the factory's UKAS accredited laboratory. The new SAC-SINGLAS laboratory in Singapore now has the same facilities for Asian customers.
In addition to this, most of Norbar's distributors offer repair , calibration & recalibration services. Several have calibration accreditation by their local standards organisations.
Norbar is owned solely by the descendants of the founder, Bill Brodey, and they remain every bit as passionate about providing customers with high quality, value for money products and services.
The company was established in 1942. The "North Bar Tool Company" (as Norbar was then known) became the first company in Britain to commercially manufacture a torque wrench. The initial demand was driven by the need for the gasket-less cylinder head of the Rolls Royce Merlin engine to be accurately tightened. Bill Brodey and his partner Ernest Thornitt obtained a license from Britain's war-time Government to begin manufacture of torque wrenches and Norbar was born.
Since then, Norbar has continued to invest in the very latest design, manufacturing and quality control technology to achieve the highest level of innovation and precision in the field of torque control equipment.
