Finger-tighten the three-jaw chuck onto a torque wrench or screwdriver, then twist either the gauge or tool to check the tool’s accuracy. A pointer on the dial shows torque as it’s measured—no batteries required. Bring these pocket-sized gauges anywhere your tools are.

All gauges come with a calibration certificate with test data traceable to either NIST or JIS, so they meet standards for accuracy. For the most accurate performance, the maximum torque you're applying should fall near the middle of the gauge's torque range. Use with hand tools only.

Measure the torque output of torque wrenches, screwdrivers, and other hand tools to ensure they deliver the right amount of torque—and check your results on a digital screen. Cycle through four units of measure on the screen, then set it to display real-time or maximum torque. These gauges have a keyless chuck that's similar to a standard drill chuck: insert the tool you're measuring and tighten the chuck by hand. They can also be used to measure the torque consistency of small rotating parts, such as motors, potentiometers, and encoders.

The gauge's memory keeps track of up to 999 different measurements.

For handheld use, the display fits inside the back of the gauge. To use the gauge on a flat surface, remove the display from the back of the gauge.

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

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.

Monitor torque as you apply it—these gauges mount between your torque tool and your fastener. Engage the fastener to track both torque and the angle of rotation for each crank of your tool (snug torque) before you've reached the final torque. This gives you a better idea if fasteners are consistently tightened than measuring torque alone. These gauges are often used with nutrunners and click-style torque wrenches in the automotive and aerospace industries. Store up to 999 maximum torque (peak) and rotation values, including the date and time of each test, or transfer to your computer to view in an Excel file. CE marked, they meet European safety standards.

For the most accurate readings, the maximum torque you're applying should fall near the middle of the gauge's torque range. They are not for use with impact tools.
