The red dot design award is one of the most
prestigious international design competitions.
Since 1955, expert juries have made awards
annually in the competition for outstanding
design achievements which set new standards

For repeating torque values, the required
torque value together with a ± tolerance can
easily be programmed, and is secure against
accidental change. This allows the user to
torque and to control his work within his
own set of specifications.
Once a fastener is torqued to within the OK
band, the BAHCO IZO-D/DF, -DM/DFM
generates identifiable signals.

Calculation of the compensating
torque when using an extension
A torque wrench is typically adjusted and
calibrated by applying a known force at the
center of the handle at a distance L1 from the
center of the driving square.
In some applications it is necessary to add an
extension to the wrench, especially when some
work has to be carried out in confined areas.
In such cases it is necessary to compensate
for this extension by reducing the program-
med set torque on the wrench according to
following formula:
