The 1/2” torque wrench delivers 50% faster installation time, replacing the hand tool or two tool installation process and providing more control to reduce the over torquing of fasteners. The 1/2” digital torque wrench provides 10-150ft-lbs of torque range and accuracy within 2% for torque critical fasteners. This battery powered torque wrench is equipped with Milwaukee ONE-KEY™ giving you the power to track, report, and manage your tool. This tool will record all of the fasteners that are saved and produce a downloadable report via ONE-KEY™ for the necessary parties requiring the data. ONE-KEY™ allows you to wirelessly connect to a smartphone to customize the tool settings, track its location, manage inventory, and lock the tool out for added security and protection for your investment.
