Fastening screws by hand causes considerable strain on wrists and muscles in the long term. The highly ergonomically shaped SoftFinish screwdriver provides a remedy, ensuring optimal transmission of hand force. The long, slender handle sizes can be used to fasten small screws quickly and firmly. There are also large handle sizes to fasten large screws which can be used to apply greater torques. The various handle sizes have also been matched to the consistently same-sized hand of screw-fastening professionals. The roll-off protection and screw symbol printed on the handle end ensure users work efficiently. Protective insulation has been integrated into the blade with the Wiha slimTECHNOLOGY specially developed for electric applications, thus ensuring blades which are up to 33 percent slimmer. This means low-lying screw and spring elements can also be easily reached. These insulated screwdrivers undergo routine individual piece testing as per the international IEC 60900 standard, as a result providing users with a tool to work safely on live parts up to 1, 000 V AC.
