Precision Instruments 1/2" Drive Split-Beam Flex Ratchet Torque Wrench

As Tesla vehicles require much higher lug nut torque specifications that standard vehicles (129 ft-lbs), many installers often make the mistake of not properly tightening lug nuts when installing wheels. After seeing several customers experience issues with incorrectly torqued lug nuts by their chosen wheel installer, we wanted to offer an option to allow for anyone to easily verify their lug nut torque.

Precision Instruments makes what are often considered the most-accurate, easiest-to-use torque wrenches in the world; the "Split-Beam" style Click Wrench, which why they're our recommended choice.

Split-Beam Click Wrenches overcome many of the problems associated with micrometer-style click wrenches in abusive environments. The wrench has few components, and all critical parts are welded together at assembly. There is no need to "work in" a C series torque wrench before using it the first time. Nor is it necessary to adjust to the lowest torque setting after use. Setting the tool requires only fingertip force since the adjustment mechanism is not under load.

Extremely Accurate-Accurate within 4% of reading from 20% of full scale to full scale. Guaranteed against defect in workmanship and materials for 1 year from the date of delivery providing that they have been used according to instructions.

Setting torque on adjustable wrenches is fast and easy because there is no spring tension on the adjustment knob.

Torque setting locks on adjustable wrenches for repetitive applications.

The wrench length is designed to provide the leverage required for maximum torque applications. The length also provides the needed reach for those-hard-to-get-at places.
