Day in and day out, mechanics routinely tighten a variety of components to specific torque values. Despite their vast experience and attention to detail, even the best and most efficient mechanic can occasionally over-tighten or under-tighten a component, leading to vehicle damage or even catastrophic failure. This Digital Torque Wrench eliminates the possibility of human error with a series of features that immediately alert the user to torque readings that are over or under entered values. Brown Line Metalworks engineered the only Digital Torque Wrench for the seasoned professional, but priced for the weekend mechanic. Brown Line Metalworks invented and patented (Patent number US 7,367,250) breakthrough technology that allows the Digital Torque wrench to deliver high-end performance and quality at an affordable retail price. Digital Torque wrench has a Double Gear Sensing System Technology (D.G.S.S.) and 8-bit microprocessor enable it to consistently produce precise torque readings of +/- 3.5 percent clockwise and counter clockwise. With a inch ratcheting drive and a range from 15 to 150 Ft/lbs, our Digital Torque Wrench is perfect for automotive use. The backlit LCD screen, green-yellow-red LEDs, and an audible buzzer allows the user to precisely monitor how much torque is being applied. User can set a target torque, and can seamlessly change from Ft/lbs to in/lbs to Nm. Maximum torque applied is displayed when done, ensuring that the user knows exactly how much torque was applied. Specially engineered plastics ensure that the wrench is resistant to common automotive oils and chemicals.
