About Torque Tools

Adjustable Torque Wrenches

Set the desired torque and the wrench indicates when it's reached with an audible click and an impulse in the grip.

Quick-Release Adjustable Torque Wrenches

No need to pull the socket off the tool—push a button to release.

Nonsparking Torque Wrenches

Made of beryllium copper, these wrenches satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present.

Electrical-Insulating Adjustable Torque Wrenches

Insulated to protect against accidental contact with live electrical circuits, these wrenches are tested to 1,000 volts to meet IEC 60900.

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%.

Slip-Release Factory-Set Torque Wrenches

These wrenches slip to disengage and stop turning the fastener when the set torque is reached, preventing overtightening.

T-Handle Slip-Release Factory-Set Torque Wrenches

Turn sockets from above when there's not room to swing a standard wrench handle.

Click-Style Factory-Set Torque Wrenches

When the set torque is reached, these wrenches signal with an audible click and an impulse in the grip.

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.

Changeable-Head Torque Wrenches

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

Adjustable Torque Screwdrivers

Torque Screwdrivers

Set the desired torque and the driver indicates when it's reached.

Torque Screwdriver and Bit Sets

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

Static-Control Torque Screwdrivers

Also known as ESD-safe screwdrivers, the handle drains static away from your application, preventing buildup from electrostatic discharge (ESD) that can damage sensitive equipment. When set torque is reached, these drivers slip to disengage and prevent overtightening.

Changeable-Shaft Torque Screwdrivers

Choose a handle based on torque, and a shaft with the size you need.

Factory-Set Torque Screwdrivers

Reach the same torque every time with factory-set screwdrivers that slip to disengage and stop turning the fastener when the set torque is reached, preventing overtightening.

Factory-Set Torque Screwdrivers
for High-Volume Assembly

Also known as impact-free torque screwdrivers, these tools minimize reaction force when the set torque is reached. They reduce user fatigue when installing many fasteners in a short period of time.

Tight-Clearance Factory-Set Torque Screwdrivers

Turn the handle like a standard torque driver and the 90° offset head reaches fasteners in tight spots. Factory-set screwdrivers ensure you reach the same torque every time.

Stubby Factory-Set Torque Screwdrivers

When working in tight spaces, these short drivers fit where others can't. They're factory set to ensure you reach the same torque every time.

Factory-Set Torque Screwdrivers for Carbide Inserts

Ensure carbide inserts are tightened to the correct torque. These tools are set to the recommended torque values for each screw size.

Changeable-Shaft Factory-Set Torque Screwdrivers

Choose a handle based on torque and change shafts to use a different size or drive style. Factory-set screwdrivers ensure you reach the same torque every time.

Torque Testers and Gauges

Data-Recording Torque Gauges

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

High-Accuracy Torque Tool Testers

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

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.
