Powerbuilt 1/2 in. Drive Digital Torque Adapter

The Powerbuilt 1/2 in. drive Digital Torque Adapter converts any standard 1/2 in. drive ratchet into an accurate digital torque wrench. Simply set the desired torque value, plug in a ratchet and socket and tighten the fastener until the digital display and audible tone indicate you've reached your target torque. You can also use it to calibrate an existing torque wrench right in your own shop or garage. Display modes include Peak, which displays and stores the max torque applied and Trace, which shows real-time torque as it is applied. Selectable for five torque units of measure: lbs. ft., lbs. in., kg-cm, kg-m and N-m.
