Stanley Assembly Technologies, (SAT) is recalling certain Mac Data Torq air-impact wrenches, part number ADT006, and Stanley Data Torq air-impact wrenches, part number 24N100006, manufactured September 23, 2015, to January 5, 2016. These computer-controlled air impact wrenches used to tighten vehicle lug nuts have software installed that may contain an error allowing the wrench to produce more torque than the amount set by the operator.
If the lug nuts were over tightened, the wheel attaching studs may fracture and the wheel may separate from the vehicle, increasing the risk of a crash.
SAT will notify the purchasers of the tools, and will recalibrate the impact wrenches and correct the software error. The recall began on August 25, 2016. Owners may contact SAT customer service at 1-614-876-3809.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
