The TorqVault from Digitool Solutions is a torque wrench that can record the torque applied to each lug nut, allowing the results to be printed on an invoice for the customer. To prevent over-torque, the wrench will show a red light if the operator goes past the torque value. The wrench will allow 2 percent over torque but nothing under torque. If the torque spec is 80 lb-ft, the wrench will allow 84 lb-ft. With a wireless range of 100', the wrench will cover many of today's tire stores, says the company. It also comes with a torque checker.
