Wiha torque screwdrivers.
Precise and high repeat accuracy.
A convincing concept.
The exact torque!
This is more and more vital for
accurateandefficientwork,
especiallywhen suchaccuracy
must be maintained and repeated –
as in the fastening and unfastening
of sensitive and expensive
components, in assembly or in final
inspections and quality assurance
applications.Theseareallperfect
tasks for the new Wiha Torque series
screwdrivers,withtheir ergonomic
handles and a unique interchangeable blade system.
The broad product range which is
specialised for industrial applications, contains the TorqueFix
model with a fixed torque value,
the TorqueVario
torque value but no scale and the
TorqueVario
window scale that displaysthetorque
value numerically.TorqueVario®-S
torque screwdriver is also available
for anti-static applicationsin ESD
environments and as a VDE insulated
variant for working on live electrical
components.

The new Wiha Torqueproductrange
is impressive with its ergonomics,
precision and functionality.All
torque screwdrivers are low weight,
robust and precise in their design,
as well as incorporating a unique
interchangeable blade system.
The blades are made from high quality
chrome-vanadium-molybdenum
steel, plastic coated and have their
maximum usable torque value
printed on them. When fastening
and the screw reaches the desired
torque, the operator will hear an
audible clickand the tool will no
longer tighten the screw. In order to
protect both the tool and the screw,
all torque handles limit the tightening
torque as well as applying a special
limit to the loosening torque. This
means that when loosening a screw
the torque will be limited to a value
that is approximately30%larger
than the tightening torque.

Patentedhandles.
SoftFinish
®
is the name of the
patented handle concept from
Wiha that forms the basis for the
TorqueFix
®
and TorqueVario®-S
torque handles. Impact-resistant
polypropylene (PP) ensures a solid
basiswithin the handle core.
This is coated with the skin-friendly
thermoplasticelastomer(TPE) by
injection moulding. The ideal
combination of materials for better

gripping and slip resistance.Thanks
to the unique, ergonomically perfect
form, the handles feel really good to
hold. The total of four handle sizes
are optimally designed for specific
torque levels.
A fundamental rule:
Low torque = small handle size.
High torque = large handle size.
Quality is the first principle.
With the mechanical precision
components of the Wiha torque
screwdrivers, an excellentrepeat
accuracyismaintained,even
with constantuse. For your safety,
every tool is inspected and calibrated
with a specially developed calibration
and labelling system before shipping.
Our works calibration takes placeby
comparison with reference standards
based upon national standards.
As a part of that, the following
standardsare fulfilled:
- EN ISO 6789
- BS EN 26789
- ASME B107.14M
The individual measured values
are recorded in a works inspection
protocol.Thisisincluded in delivery

industrial quality, long service lives
and a high level of functional safety
are achieved. eaasyTorque

The loosening torque is not limited.
If a blade becomes blunt, it can be
easilyand quicklyreplaced.That is
both practical and cost-efficient.
