Torque Analyzers | McMaster-Carr

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.

High-Accuracy Torque Tool Testers

These testers have a digital display and are accurate to ±1%.

Torque Tool Testers for Torque Screwdrivers

Calibrate torque screwdrivers, both hand and non-impact electric styles, on your production line and put an end to fasteners loosening or failing from under or over tightening.

Torque Testers for Torque-Limiting Power Tools

Keep torque-limiting power tools, such as air-powered tools and impact drivers, calibrated and prevent fasteners from loosening or failing because of under or over tightening.

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.

Opening-and-Closing Torque
Testers for Caps and Knobs

Measure the twisting force needed to tighten tops, loosen lids, and turn potentiometer knobs or valve wheels.

Data-Recording Torque Gauges

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

Robot-Ready Force Torque Sensors

Mount these sensors between a robot arm and a tool for precise control during delicate tasks, such as sanding or assembling small parts.

Fastening Tools

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.

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.

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.

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.
