Features:
• 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).
• Adjustment Lock: all models feature a lock to prevent accidental adjustment of the set torque.
• Versatile Ratchets: the tough ratchets are reversible and a narrow engagement angle of 6° (5° on TT20 & TT50 models) 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.
• The handle material and lens resist chemicals in common usage in the automotive, aviation and industrial environments.
• Bi-directional Torque: the ratchets are also 'push through' meaning that these wrenches will provide torque control in both the clockwise and anticlockwise directions (not available on TT20 & TT50 models).
