Click-type torque bar engineered for controlled right- and left-hand tightening with a declared torque accuracy of ±3%. Large, high-contrast scale improves setting visibility while the mechanism increases torque-adjusting speed by approximately 40% for faster, repeatable settings. Handle and lens use materials selected for resistance to chemical agents commonly found in automotive, industrial and aviation workshops. A red o-ring visually indicates when the wrench is unlocked for adjustment; a built-in recalibration reminder flags service intervals at 3, 6, 9 and 12 months.
