Torque Wrenches
TTi Wrench
Models 20 N.m and 50 N.m (180 lbf.in and 35 lbf.ft)
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.
• 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 be achieved 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.
•
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.
•
Versatile ratchets: the tough ratchets are reversible and have a narrow engagement angle of 5º to
allow easy positioning of the tool in the tight confines of today’s vehicles and machines.
•
Can also be supplied as Fixed Head (TTf) and Female ended Torque Handles (TTfth), for further
details see page 15.
Norbar Non-Magnetic torque wrenches are
designed primarily for the medical MRI scanner
market. However, they will prove invaluable where
ever a torque wrench has to be used in the
presence of a strong magnetic field.There are
currently four models:
1 - 20 N.m, 3/8” sq. dr. Part No. 13292
1 - 20 N.m, 1/2” sq. dr. Part No. 13585
