TEKTON Set Drive Beam Torque Wrench 19.18-ft/lb to 258.15-ft/lb

Tekton 72-Tooth Split Beam Torque Wrenches are easy to read and easy to set. Quickly turn to the desired torque value with a smooth thumbscrew adjustment. Teeth inside the cover lock the torque setting in place while you are using the wrench. Because there's no internal tension when the wrench is at rest, you don't need to turn it to the lowest setting for storage. Each Tekton Split Beam Torque Wrench is calibrated according to the ASME B107.300-2010 standard. The detailed test results are recorded on the included certificate. The certificate includes the initial accuracy, expected future accuracy, and the wrench's serial number. All torque wrenches lose accuracy with repeated cycles. The expected future accuracy information helps you evaluate when recalibration may be necessary. Each wrench is engraved with a unique serial number that corresponds to its certificate of calibration. The conversion scale on the handle of the torque wrench offers a quick reference for converting ft.-lb to Nm. The handle is made from an impact-resistant nylon with nonslip polypropylene grip. The head of the torque wrench has a 10-degree flex joint, offering clearance to work around nearby obstructions. As with any flex-head torque wrench, some accuracy is lost when the handle is not in the straight position, so this feature should only be used when needed.
