Manual screwing places significant strain on wrists and muscles over time. The specially ergonomically shaped SoftFinish® screwdriver alleviates this by ensuring optimal transfer of hand force. With the long, slim grip sizes, small screws can be securely and quickly driven in. For driving larger screws, there are larger grip sizes that can apply higher torque. Additionally, the various grip sizes are tailored to the consistently sized hands of professional screwdrivers. The roll-off protection and the printed screw symbol at the end of the handle ensure efficient work. The Wiha slimTECHNOLOGY, specifically developed for electrical applications, integrates the protective insulation into the blade, allowing for blades that are up to 33% slimmer. This enables easy access to deep-seated screw and spring elements. The insulated screwdrivers undergo a piece testing according to the international standard IEC 60900, allowing for safe work on live parts up to 1,000 V AC. DIN ISO 2380. tz 3.5 mm x 100 mm.
