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.

Torque-Measuring Wrenches

Measure with an accuracy of ±2%.

High-Accuracy Torque-Measuring Wrenches

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

Economy Torque-Measuring Wrenches

These wrenches have an accuracy of ±2.0%.

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.
