This slimFix twinset comprises a 3.5mm sloted and a 2Pz screwdriver. Produced to give better access to recessed screws, particularly in terminal blocks when a thick insulation jacket often prevents the tip from reaching the screw head. Wiha slimFix technology ensures these screwdrivers fully conform to the very strict DIN standards and European and International IEC and VDE standards for use on all types of common electrical work. Fully tested up to 10,000 Volts DC and guaranteed to 1,000 Volts AC. These are industrial/professional tools.
