    Digital Torque-Measuring Screwdrivers

    Image of Product. Front orientation. Torque Screwdrivers. Digital Torque-Measuring Screwdrivers .
    A green light and a beep alert you when you've reached 90% of your set torque, and a steady tone sounds once you've hit your target. Set your torque in cNm, cm-Kg, or in.-lbs. and quickly check the LCD for real-time measurements along the way. A red light warns if you begin to overtighten. In addition to applying the correct torque to a fastener, these screwdrivers can help determine fastener torque specifications and identify the torque required to loosen tightened fasteners. They store up to nine torque settings to save time when working on multiple fasteners. They're compatible with any bit that has a 1/4" hex shank. All require one AAA battery (included). To save battery power, the display turns off after five minutes of idle time. You can also turn the display off manually.
    Accurate to within 2% of the set torque in the clockwise direction, and 3% in the counterclockwise direction, these screwdrivers are more precise than standard torque screwdrivers. All screwdrivers come with a calibration certificate from the manufacturer.
    Calibration Certificate Traceable to NIST—Screwdrivers with calibration certificate traceable to NIST have passed a test for accuracy.

    Attach a socket to the 1/4" square drive tip to turn hex nuts and hex head screws. The dial on these drivers shows how torque measurements change as you turn. Use to fasten to a specific torque, determine fastener torque specifications, and identify the torque required to loosen tightened fasteners. To use with screwdriver bits, add a bit adapter. Drivers come with a calibration certificate that is traceable to NIST and states the product has passed a test for accuracy.
    Note: The accuracy ratings do not apply to the lower 20% of the torque range.
    Memory Pointer—Drivers with memory pointer indicate the maximum torque reached.
    1/4" Female Square Drive in Handle—Drivers with 1/4" female square drive in handle allow you to attach a T-handle or ratchet to the end for extra leverage when applying high torque.

    Eliminate the need for multiple bulky tools with these bit adapters. At less than 3 inches long, these compact adapters convert 1/4" bit screwdriver handles and 1/4" bits into torque screwdrivers so you can fasten to a specific torque. Insert your drive handle and turn clockwise until the hash marks line up with the torque value you need. Not for use with power tools.
