The Impulse 1/2 torque wrench provides precise torque when installing bolts, nuts and other fasteners. It avoids the problems of under- or over-tightening fasteners, which can lead to failure or damage.
Simple to use, it requires prior configuration of the desired torque by adjusting a 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.
