Wera 8790 A Zyklop VDE Insulated 1/4" Drive Hexagon Socket 1/4" 4mm

The Wera 8790 A Zyklop VDE Insulated Socket in 4mm is a compact 1/4" drive hexagon socket designed for precision work in live electrical environments. The 4mm size is ideal for smaller fasteners commonly encountered in electrical panels, control gear, and instrumentation, where both accuracy and safety are paramount. Each socket is individually tested to IEC 60900 at 10,000 V, providing full confidence for approved working voltages up to 1,000 V. The dual-layer insulation design features a yellow inner core beneath the distinctive outer red VDE layer — if the outer layer is ever damaged, the yellow core becomes immediately visible, alerting the user before work continues. A protective plastic sleeve guards sensitive surfaces against marking or scratching during use.
