Accurate to within ±1%, these torque testers 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 tester with the included square drive connection and turn. These testers 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 tester's torque range.

Bench-top testers can be mounted to your work surface. Those with a gooseneck display can be bent until you can clearly see the test results. Mount these testers to your workbench with a mounting bracket (sold separately). Or, carry them where they’re needed using the included case.

Portable testers are lightweight and easy to move around your facility. Their touch-screen display makes it easier to navigate through different menus than testers with a digital-screen display. To view data in a CSV file, pop out the tester’s SD card and plug it into your computer. You can also transfer data by connecting the tester directly to your computer with the USB cord. To use these testers with nonimpact power tools, they include at least one socket screw adapter. These testers meet ISO 17025, so they’ve been checked in a laboratory that was evaluated for accuracy.

Monitor torque as you apply it—these testers 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 testers 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 tester's torque range. They are not for use with impact tools.

Testers with a USB connection transfer data directly to your computer with the included cord. These testers last up to 10 hours on a single charge.

Testers with a Bluetooth connection wirelessly transmit data to a computer as you measure. You can also remotely set snug torque, or when these testers 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.

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 testers 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 tester's torque range. A track mode lets you monitor fluctuating torque. For quick pass/fail testing, these testers 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.

Testers that meet ISO 17025 have been checked in a laboratory that was evaluated for accuracy.

Testers with automatic screw release reduce time between tests by returning the test screw to its starting position once torque is removed.

Use data acquisition software and a USB cable (each sold separately) to analyze results and connect to computers, laptops, or tablets that run on Microsoft Windows.

Testers cannot be sold to the listed areas due to energy efficiency regulations.

Measure the twisting force needed to tighten or loosen caps and knobs with these torque testers. Four adjustable gripping posts clamp round and irregularly-shaped containers. Twist the top by hand to measure force or use it to calibrate your capping machine, so it applies the right amount of force in a production line. For the most accurate performance, the maximum torque you’re applying should fall near the middle of the tester’s torque range. If you accidentally exceed the torque range, these testers have overload protection to prevent damage to the measuring system.

View torque measurements, change operating modes, and switch units of measurement on the LCD screen. Store data on the microSD card, transfer it to your devices via Bluetooth or USB, or print using the DB9 cable. The I/O cable connects to controllers to operate other devices dependent on torque force readings.

Testers with a calibration certificate with test data traceable to NIST meet standards for accuracy.

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.

Wrench-attachable sensors fit between your wrench and socket. Use with hand tools only.

Hand-turned sensors don't require a tool; place into your socket and turn them with your hand.

The clutch slips when the set torque is reached to prevent overtightening and damaging fasteners. To set torque, turn the adjustment collar.

A green light and a beep alert you when you've reached 90% of your set torque, and a steady tone sounds once you've hit your target. Set your torque in cNm, cm-Kg, or in.-lbs. and quickly check the LCD for real-time measurements along the way. A red light warns if you begin to overtighten. In addition to applying the correct torque to a fastener, these screwdrivers can help determine fastener torque specifications and identify the torque required to loosen tightened fasteners. They store up to nine torque settings to save time when working on multiple fasteners. They're compatible with any bit that has a 1/4" hex shank. All require one AAA battery (included). To save battery power, the display turns off after five minutes of idle time. You can also turn the display off manually.

Accurate to within 2% of the set torque in the clockwise direction, and 3% in the counterclockwise direction, these screwdrivers are more precise than standard torque screwdrivers. All screwdrivers come with a calibration certificate from the manufacturer. Screwdrivers with calibration certificate with test data traceable to NIST include the test measurements that confirm accuracy.

A dial shows how torque measurements change as you turn the driver. Use these tools to fasten to a specific torque, determine fastener torque specifications, and identify the torque required to loosen tightened fasteners.

Calibration certificate traceable to NIST states the product has passed a test for accuracy.
