Wera 8740 A VDE HF bit socket 4 mm, 1/4″

Wera 8740 A VDE HF bit socket 4 mm, 1/4″. Insulated Zyklop bit socket for hexagon socket screws, with a 1/4-inch square drive. The HF holding function retains the screw on the tip, reducing the risk of dropping it while positioning it in confined or hard-to-reach locations. Every tool is individually tested at 10,000 V to IEC 60900; the approved working voltage is up to 1,000 V. A yellow inner insulation layer becomes visible if the red outer layer is damaged. The plastic sleeve helps protect working surfaces. Selling unit: one bit socket. Larger Hex-Plus contact surfaces help reduce rounding of the screw recess.
