Socket designed with your safety in mind when working on Low Voltage Electrical Devices. Made using modern Hybrid Technology, which combines insulating material with working heads made of the highest quality tool steel. The insulating material that forms the basis for the construction of this tool is the patented, innovative INLLOYTM material. The dielectric properties of this material (0.005 mA leakage current at 10 kV), combined with enormous mechanical strength for plastics, 24 Nm for size 8, provide maximum safety when Live Working.
