Force 6473268N 3/8"DR. Insulated Torque Wrench is Ideal for use on hybrid and electric vehicles. This torque wrench uses a 'slipper' type release mechanism instead of a traditional click mechanism. When the wrench arrives at the set torque it will slip and continue to slip until the load is removed. Any subsequent application of torque will result in the wrench continuing to slip ensuring the set limits cannot be accidently overridden as can happen with more traditional click type wrenches.
