    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.

    High-Accuracy Horizontal-Scale Torque-Measuring Wrenches

    Trust the precision of your measurements—these wrenches are accurate to ±2%. The scale has a main pointer that shows torque as it’s being applied and a memory pointer that indicates the maximum torque reached. Use to determine fastener torque specifications as well as to identify the torque required to loosen tightened fasteners. These wrenches come with a calibration certificate, which includes test measurements that confirm accuracy.
    Note: Accuracy ratings do not apply to the lower 20% of the torque range.
