Accuracy key to torque wrench
March 1st 2008 The key objectives for Norbar
Torque Tools in designing its
latest torque wrench were that it
should be durable and stay in
calibration for as long as possible,
even when used regularly in tough
workshop conditions.
The result is a wrench that uses
an improved mechanism, yet
retains some of the elements from
the original tried-and-tested
design. Adjustment is simple with
the coarse scale on the handle
and a micrometer for fine setting.
The new Norbar wrench moves
with fingertip control over the
entire length of the scale.
A new grip design provides
comfort and has good slipresistance
in all conditions.
The TruTorque models cover a
torque range from 20 to 300N.m in
five models. All sizes offer bidirectional
torque control,
essential for left-hand threads and
for controlling the maximum
torque when undoing bolts.
Ratchets are reversible for ease of
positioning and have a narrow
engagement angle so they can be
used in tight spaces.
The Trutorque is accurate to
±3% of reading and each wrench
is supplied with a traceable
calibration certificate. A lock is
incorporated to prevent accidental
adjustment of set torque. More articles from Norbar Torque Tools Limited: |
