Ratchet Wrenches and Handles

Flex-Head Wrench Handles

Pivot the head for access to fasteners in tight spots.

Cushion-Grip Flex-Head Wrench Handles

A rubber coating provides a comfortable grip.

Adjustable-Length Flex-Head Wrench Handles

Extend the shaft for additional length.

Sliding T-Style Wrench Handles

Position the head anywhere along the handle.

L-Style Wrench Handles

The L shape provides clearance when reaching over obstructions.

Ratchet Wrenches

A ratchet mechanism allows you to turn fasteners without removing and repositioning the wrench.

Cushion-Grip Ratchet Wrenches

The handle is covered in rubber for a comfortable grip.

Quick-Release Ratchet Wrenches

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

Sealed-Head Ratchet Wrenches

A gasket seals in permanent lubrication and keeps out dirt, dust, and moisture.

Adjustable-Length Ratchet Wrenches

The shaft on these wrenches extends and locks.

Fast-Driving Ratchet Wrenches

Twist the grip to rapidly turn a socket before final tightening or to remove a fastener once loosened. The handle also swings like a traditional ratchet wrench.

Replaceable-Head Ratchet Wrenches

When the ratchet head becomes worn or damaged, change it out for a new one.

Tapered-Handle Ratchet Wrenches

Also known as a construction or spud handle, wrenches use the pointed end to align bolt holes.

Nonsparking Ratchet Wrenches

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

Electrical-Insulating Ratchet Wrenches

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

Flex-Head Ratchet Wrenches

Pivot the head to access fasteners in tight spots.

Quick-Release Flex-Head Ratchet Wrenches

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

Offset Flex-Head Ratchet Wrenches

The 20° offset head provides clearance when reaching over obstructions.

Tight-Clearance Ratchet Wrenches

Rather than teeth, these wrenches use a series of rollers to engage the ratchet, enabling work in the tightest of spaces. Also known as silent ratchets, they don't make the traditional click sound when turned.

Fingertip Ratchet Wrenches

Turn sockets in the most confined spaces.

Bolt-Through Ratchet Wrenches

Bolts and threaded rod pass through these wrenches when used with bolt-through sockets.

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.

Impact Wrenches

Also known as impact drivers, use these tools with impact sockets to break frozen bolts and screws free. Strike with a hammer to tighten and loosen fasteners.

Air-Powered Wrenches

Light Duty Air-Powered Impact Wrenches

These tools are suitable for general shop, maintenance, and automotive work.

Heavy Duty Air-Powered Impact Wrenches

Built for durability, these high-performance tools handle the demands of high-volume production and tough maintenance applications.

Standard Duty Air-Powered Impact Wrenches

Use these wrenches for medium-volume production, general maintenance, and construction applications.

Standard Duty Air-Powered Ratchet Wrenches

Use these tools for general shop applications.

Heavy Duty Air-Powered Ratchet Wrenches

Built for durability, these wrenches handle the demands of high-volume production and tough maintenance applications.

Cordless Wrenches

Cordless Impact Wrenches

Cordless Ratchet Wrenches

Electric Impact Wrenches

Impact Hex Bit Socket Sets

Use these sockets as an alternative to a screwdriver or L-key. They are made to withstand the high torque and force of impact tools.

External Torx-Plus Sockets

Designed to fit on external Torx-Plus fasteners, often found on pickup trucks, these sockets have squared lobes that resist slipping at high torque.

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.
