Knipex 98 37 5/16" KN | Hex Socket, 3/8", 5/16", 1000V Insulated

An Insulated Socket is a specialized tool designed for safely working on electrical systems and components, particularly in environments where there is a risk of electric shock. These sockets are constructed with a non-conductive insulating material, typically a high-dielectric plastic or rubber coating, which covers the metal body to protect users from electric currents up to a specified voltage rating.
