The Kabeldon VHB 68 is an insulated hex bit spanning 6 mm and 8 mm sizes, designed to be driven by a torque wrench with a 1/2" square drive. The insulating body permits torque-controlled fastening on live or nearby-live equipment while retaining traceable torque values. Typical applications include compression-lug and busbar work on low- and medium-voltage switchgear.
