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.

Flex-Head Adjustable Torque Wrenches

Pivot the head to access fasteners in tight spots.

Quick-Release Adjustable Torque Wrenches

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

No-Reset Adjustable Torque Wrenches

Unlike most torque wrenches, you don’t have to return the torque setting to the lowest value after use. These tools are also known as split-beam torque wrenches.

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%.

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%.

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 Multipliers

Apply more torque than your wrench can deliver on its own. Use a multiplier with a torque wrench to ensure you do not exceed the maximum input torque.

Mountable Torque Multipliers

Anchor these multipliers for added stability.

Low-Profile Torque Multipliers

Get the force of a standard torque multiplier without the bulk. These multipliers are less than 2" high, so they fit where you have limited clearance above a fastener.

Torque-Limiting Air-Powered Wrenches

Set torque and the wrench will prevent you from exceeding it. These are also known as nutrunners.

Socket Adapters and Extensions

Adjustable Torque-Limiting Socket Adapters

Set a desired torque within the range.

Factory-Set Torque-Limiting Socket Adapters

Already set to a specific torque limit, these adapters audibly click and release when you reach that setting to prevent overtightening.

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.
