Wera 8740 A HF Zyklop VDE Insulated 1/4" Drive Hexagon Bit Socket

The Wera 8740 A HF Zyklop VDE Insulated 1/4" Drive Hexagon Bit Socket in 4mm offers a versatile mid-small size well suited to a wide variety of electrical and mechanical applications involving hexagonal socket head screws. The 4mm hex is a common fastener size found across electrical panels, junction boxes, and light engineering assemblies. Its holding function grips screws securely during insertion, reducing the risk of losing fasteners in confined or awkward working areas. The two-component insulation system — a yellow inner core beneath the outer red VDE layer — provides immediate visual indication of any insulation damage, keeping you informed and protected at all times.
