    Measure the force of hand and non-impact electric torque screwdrivers to keep fasteners from failing due to under or overtightening. A chuck-like adapter simulates your fastener joint during testing. These gauges record the first time you reach the maximum torque (peak down), the maximum torque (peak), and torque as it's measured (real-time). For the most accurate performance, the maximum torque you're applying should fall near the middle of the gauge's torque range. A track mode lets you monitor fluctuating torque. For quick pass/fail testing, these gauges have programmable high/low set points with lights and an alarm. They include a calibration certificate with test data traceable to NIST that states they have passed tests for accuracy.
    ISO/IEC 17025—Gauges that meet ISO/IEC 17025 have been checked in a laboratory that was evaluated for accuracy.
    Automatic Screw Release—Gauges with automatic screw release reduce time between tests by returning the test screw to its starting position once torque is removed.
    Cannot Be Sold To—Gauges cannot be sold to the listed areas due to energy efficiency regulations.
    Cords—Use data acquisition software and a USB cord (sold separately) to analyze results and connect to computers, laptops, or tablets that run on Microsoft Windows.

    High-Accuracy Torque Tool Gauges

    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.

    Check the accuracy of torque wrenches and screwdrivers—place your tool onto the gauge with the included square drive connector and turn. The main pointer shows torque as it's measured; Gauges with memory pointers show the maximum torque reached. Use these gauges with hand tools only.
    Note: For the most accurate performance, the maximum torque you apply should fall near the middle of the gauge's torque range.

    Rotary Torque Gauges

    Image of Product. Front orientation. Torque Gauges. Rotary Torque Gauges.
    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.
    USB-B Connection—Gauges with a USB connection transfer data directly to your computer with the included cord. These gauges last up to 10 hours on a single charge.
    Bluetooth Connection—Gauges with a Bluetooth connection wirelessly transmit data to a computer as you measure. You can also remotely set snug torque, or when these gauges starting measuring the torque applied with each rotation. They last up to 8 hours on a single charge with Bluetooth on and 10 hours with it off.

    Data-Recording Torque Gauges

    Use these gauges with changeable sensors and square-drive sockets (sold separately) to display, collect, and download torque readings. They display torque as it's measured and the maximum torque reached. Gauges can also be used to convert any hand-turned square drive tool into a precise torque-measuring tool. For the most accurate performance, the maximum torque you're applying should fall near the middle of the gauge's torque range.
