The Sealey Premier 1/2″ Drive Insulated Torque Wrench is a professional-grade torque wrench designed specifically for electrical safety when working on live systems. Featuring full insulation to BS EN IEC 60900:2018, this tool protects technicians from electric shocks up to 1500V DC and 1000V AC, making it essential equipment for hybrid and electric vehicle technicians as well as electricians working on high-voltage installations. Constructed with a Chrome Vanadium steel reversible 60-tooth ratchet head, the wrench delivers precise torque application in both directions. The impact-resistant polycarbonate tubing combined with injection-moulded nylon thermoplastic provides complete insulation whilst maintaining durability. The micrometer-type adjustment system allows accurate torque settings with scales graduated in both lb.ft and Nm for versatility across different specifications. Calibrated to BS EN ISO 6789:2017 standards with an accuracy of ±1% at 21°C, this torque wrench delivers reliable, repeatable results. The tool remains functional in extreme conditions, withstanding temperatures from –40°C to +70°C. Each unit is supplied with a test and calibration certificate, providing documented proof of accuracy for quality assurance and compliance requirements. The 20-100Nm range makes it ideal for automotive fasteners, electrical installations, and general maintenance applications where both precision torque control and electrical safety are critical.
