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.

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 with every torque screwdriver.

As with its big brother TorqueFix
, the easyTorquetorquehandlecan be combined with colour-coded interchangeable blades from the Torquerange.Becauseofrobust, industrial quality, long service lives and a high level of functional safety are achieved. eaasyTorque screwdrivers are characterisedbya release accuracyof±10%. The loosening torque is not limited. If a blade becomes blunt, it can be easilyand quicklyreplaced.That is both practical and cost-efficient.
