Sometimes trying to get to a fastener and applying the proper torque is quite difficult. Most ratchets come with a pivoting head. Why not a torque wrench? Ours comes with a long list of features. The head contains 48 ratcheting teeth and pivots 15° in each direction (30° total). This provides excellent access in tight areas for more accuracy. The easy to read LCD display reads in ft/lbs and Nm. The wrench emits an intermittent beep and a green LED blinks once you are within 25% of the setting. A red LED illuminates and an audible constant beep alerts you that the torque is set. The 3/8" wrench is rated from 7.4-99.6 ft/lbs (10-135Nm). The 1/2" wrench is rated from 14.8-147.0 ft/lbs (20-200Nm). Both are accurate within +/- 0.5%. Each wrench is individually serial numbered (so you know it's yours), includes a calibration certificate calibrated to ISO 17025 & ISA 6789-2008 international standards and comes in a custom molded case to keep it protected. Uses six AAA batteries that I include of course!
