McMaster 4457A44 High-Accuracy Torque Tool Gauge, Bench Top, 3/8" Square Drive, 60 to 600 in.-lbs. Torque

Bench Top, 3/8" Square Drive, 60 to 600 in.-lbs. Torque

Accurate to within ±1%, these torque gauges are often used to check the accuracy of torque wrenches and screwdrivers on assembly lines. They come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. To test, place your torque wrench or screwdriver onto the gauge with the included square drive connection and turn. These gauges display torque as it's measured and the maximum torque reached. For accuracy when testing click-style wrenches, they also show the first torque peak reached. They’re not for use with impact or pulse tools.

Note: For the most accurate readings, the maximum torque you're applying should fall near the middle of the gauge's torque range.

Bench Top — Bench-top gauges can be mounted to your work surface.
