About Torque Tools

Adjustable Torque-Limiting Socket Adapters

Set a desired torque within the range.

Factory-Set Torque-Limiting Socket Adapters

Adapters are set to a specific torque and cannot be adjusted.

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.

Impact Torque-Limiting Socket Adapters

Prevent overtightening that can damage fasteners. These adapters spring back slightly when the set torque is reached.

Impact Torque-Limiting Socket Adapter Sets

Prevent overtightening that can damage fasteners. These adapters spring back slightly when the set torque is reached.

Changeable-Head Torque Wrenches

Change heads to use these tools as an open-end, box, square drive, or hex-key wrench.

Torque Screwdriver and Bit Sets

These sets include an adjustable torque driver, bits for different drive styles, and a socket adapter.

Changeable-Shaft Torque Screwdriver Sets

Set includes a handle and six shafts. Remove and replace the shaft to use a different size or drive style.

Data-Recording Torque Gauges

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

Square Drive Torque Tool Testers

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

High-Accuracy Torque Tool Testers

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

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 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.

Torque Testers for Torque-Limiting Power Tools

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