An Impulse 1" torque wrench applies precise torque. It ensures that bolts, nuts and other fasteners are tightened with the appropriate force. This avoids the risk of under- or over-tightening, which can lead to failure or damage. Simple to use, it requires prior configuration of the desired torque by adjusting the setting ring. Once set, the wrench emits a click or tactile sensation when the preset torque is reached, allowing the user to stop at the right moment. *When the tool is at rest, always leave the ring at zero so as not to leave the mechanism under tension.
