Features and BenefitsAccuracy: +- 4% tolerance of set valueIts ergonomic handle is comfortable and easy to gripIts graduated scale allows quick and easy reading of torqueMade of chrome-plate steelOffers strength and durability to withstand repeated use and heavy loadsThe 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.SpecificationsWarranty1 year warrantyDrive size1/2”Maximum torque (ft-lb)48-247.2Maximum torque (Nm)50-350CertificationsDIN ISO 6789, ASME B107.300-2010ColorSilverIncludedPlastic case transportMaterialsSteelProduct dimensions – LxWxH (inches)22 x 1.8 x 1.4DocumentsUser manual
