Product Description: This is a preset torque wrench essential for tightening wheel nuts on passenger vehicles. It comes with three sizes of sockets with sleeves that are less likely to damage the wheels, and an extension bar. You can set the torque value by turning the grip, and lock the set value at the grip end. When the set value is reached, it will notify you with a light click and sound. 【Clear Steel】 This is Astro Products' first attempt, using clear coating on unpainted iron to bring out the "taste" of the iron itself while also making it easy to handle. ■Product Specifications: [Set Contents] ・Torque wrench, wheel sockets 17, 19, 21mm, extension bar 150mm, storage case [Torque Wrench] ・Overall Length: 420mm ・Weight: 1kg ・Setting Range: 30～180Nm ・Minimum Graduation: 1Nm ・Accuracy: ±4% ・Drive: 1/2DR (12.7mm) ・Gear Count: 24T [Sockets] ・Overall Length: 78mm ・Material: Chrome Vanadium [Extension Bar] ・Overall Length: 150mm ・Material: Chrome Vanadium
