About Torque Tools

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.

Electrical-Insulating Torque Screwdrivers

An insulated handle and shaft protect against shock from accidental contact with live electrical circuits. These tools are tested to 1,000 volts to meet IEC 60900 standards. When set torque is reached, these drivers signal with an audible click.

Changeable-Shaft Torque Screwdrivers

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

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.

Square-Drive Torque Screwdrivers

Attach a socket to the 1/4" square drive tip to turn hex nuts and hex head screws. When set torque is reached, these drivers signal with an audible click.

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.

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.

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.

Clean Room Factory-Set Torque Screwdrivers

Rated for ISO Class 5 (Fed. Std. Class 100) clean rooms, these tools have a sealed handle to keep lubrication in and contaminants out. Factory-set screwdrivers ensure you reach the same torque every time.

Electric Torque Screwdrivers

Set torque and the clutch slips to prevent you from exceeding it.

High-Precision Electric Torque Screwdrivers

The motor shuts off when the set torque is reached to prevent overtightening and damaging fasteners. These tools provide the most torque control of any electric screwdriver.

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.

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.

Air-Powered Torque Screwdrivers

Set torque and the clutch slips to prevent you from exceeding it.

High-Precision Air-Powered Torque Screwdrivers

The motor shuts off when the set torque is reached to provide the most torque control of any air-powered screwdriver.

Torque-Measuring Bit Adapters

Eliminate the need for multiple bulky tools with these bit adapters. At less than 3 inches long, these compact adapters convert ¼” bit screwdriver handles and ¼” bits into torque screwdrivers so you can fasten to a specific torque.

Cordless Screwdrivers

Rechargeable batteries keep these tools powered wherever you need them.

Torque Wrenches

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%.

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%.

T-Handle Slip-Release Factory-Set Torque Wrenches

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

Slip-Release Factory-Set Torque Wrenches

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

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.

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.

Torque Multipliers

Mountable Torque Multipliers

Anchor these multipliers for added stability.

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.

Torque-Limiting Air-Powered Wrenches

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

Changeable-Head Torque Wrenches

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