The Ascot Supply Split Beam Torque Wrench is designed for professional, heavy duty use. It has an accuracy of +/- 4 percent with no need to return to zero after use due to its non-coil spring mechanism. This results in extended tool life. Its knob-type torque adjustment provides fast and energy-saving efficiency and the torque setting can easily be read through the window scale. It also has an oil-resistant TPR cushion handle for user comfort and ease of control. The user will hear a loud click sound and strong impulse when the required torque is reached, preventing inaccuracy.
