Norbar proudly celebrates 67 years of torque wrench manufacture with the launch of the new range - TruTorque.

In engineering this new range, Norbar has paid close attention to accuracy, ease of setting and comfort in use.

Durability has been a primary development goal - both in terms of the lifetime of components and longevity of calibration accuracy. Cycle testing of wrenches at full torque was a key element of the development process and, in total, several million tightening cycles were accumulated. The result is a product that you can use with complete confidence that you have the best tool for the job.

    Technical Specification
  • 长度: 230 mm
  • 驱动方头尺寸: 1/4"
  • 重量: 0.4 Kg
  • 棘轮直径: 30 mm
  • 每转啮合齿数: 72
  • Accuracy: +/-3% of reading exceeds all international standards for torque wrenches. Each wrench is supplied with a traceable calibration certificate.
  • Micrometer Scale for simple and error free setting. (On dual scale wrenches, the micrometer increment applies to the N·m scale.)
  • Quick and Light Adjustment: adjustment over the entire scale can quickly be achieved and with minimal effort in approximately ten complete turns (exact number varies by model).
  • Versatile Ratchets: the tough ratchets are reversible and have narrow engagement angles of 5 degrees to allow easy positioning of the tool in the tight confines of today's vehicles and machines.
  • Comfortable, Durable Handle: the handle is constructed using two materials; a base material for strength overlaid with a soft feel grip for comfort and slip resistance.
  • Adjustment Lock: all models feature a lock to prevent accidental adjustment of the set torque.
