About Torque Tools

High-Accuracy Torque Tool Testers

Accurate to within ±1%, these torque testers are often used to check the accuracy of torque wrenches and screwdrivers on assembly lines.

Square Drive Torque Tool Testers

Place your tool and the included square drive connector on the tester and turn.

Chuck-Style Torque Tool Testers

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.

Chuck-Style Digital Torque Tool Testers

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.

Torque Tool Testers for Torque Screwdrivers

Measure the force of hand and non-impact electric torque screwdrivers to keep fasteners from failing due to under or overtightening.

Opening-and-Closing Torque
Testers for Caps and Knobs

Measure the twisting force needed to tighten or loosen caps and knobs with these torque testers.

Torque Testers for Torque-Limiting Power Tools

Calibrate torque-limiting power tools such as air-powered and impact drivers.

Square Drive Connectors for Torque Tool Testers

Use these connectors to test male square drive tools on torque testers that have a male square drive.

Rotary Torque Testers

Monitor torque as you apply it—these testers mount between your torque tool and your fastener.

Data-Recording Torque Gauges

Use these gauges with changeable sensors and square-drive sockets to display, collect, and download torque readings.

Torque Sensors

Measure and record manually applied torque. These sensors convert torque into an electrical signal that your computer or programmable logic controller (PLC) can read.

Torque Screwdrivers

Square Drive Torque-Measuring Screwdrivers

Attach a socket to the 1/4" square drive tip. These tools have a dial that shows how torque measurements change as you turn the driver. Use to fasten to a specific torque, determine fastener torque specifications, and identify the torque required to loosen tightened fasteners.

Torque-Measuring Screwdrivers

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.

Digital Torque-Measuring Screwdrivers

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.

Electric Torque Screwdrivers

Set torque and the clutch slips to prevent you from exceeding it.

Square Drive Sockets and Ratchet Wrenches

Economy Torque-Measuring Wrenches

These wrenches have an accuracy of ±2.0%.

High-Accuracy Torque-Measuring Wrenches

Trust the precision of your measurements—these wrenches are accurate to ±1%.

Torque-Measuring Wrenches

Measure with an accuracy of ±2%.

Data-Recording Torque-and-Angle
Measuring Wrenches

The most advanced torque wrenches we offer, these tools store and recall up to 1,500 torque and angle measurements.

Dial Torque-Measuring Wrenches

A main pointer on the dial shows torque as it’s being applied and a memory pointer indicates the maximum torque reached.

High-Accuracy Horizontal-Scale
Torque-Measuring Wrenches

Trust the precision of your measurements—these wrenches are accurate to ±2%.

Horizontal-Scale Torque-Measuring Wrenches

Measure with an accuracy of ±7%.

Torque-and-Angle Measuring Socket Adapters

A digital display shows how torque measurements change as you turn the wrench. Set the desired torque and angle—lights and an audible alarm indicate when target has been reached or exceeded.
