Technicians working on hybrid and electric vehicles face a unique risk: standard torque wrenches offer no protection against live electrical systems, where a slip can be life-threatening. The Sealey STW804 Insulated Torque Wrench is fully insulated to BS EN IEC 60900:2018, providing protection from electric shocks up to 1500V DC and 1000V AC, making it safe for live working on modern electric and hybrid vehicle systems. Built with a Chrome Vanadium steel reversible 60-tooth ratchet head on a 1/2" square drive, it covers a torque range of 12-60Nm (9-44lb.ft) with a micrometer-type adjustment scaled in both Nm and lb.ft. Accuracy is ±1% at 21°C, calibrated in accordance with BS EN ISO 6789:2017. The impact-resistant polycarbonate tubing and injection-moulded nylon thermoplastic construction ensure total insulation throughout, and the tool remains functional in temperatures from -40°C to +70°C. A test and calibration certificate is included, and the wrench is backed by a lifetime guarantee. Overall length is 350mm.
