Tight-Clearance Offset Sockets

Often used with an extension, these sockets turn fasteners and fittings in obstructed areas that a regular socket can't reach. They are also known as crowfoot wrenches.

Box-End Tight-Clearance Offset Sockets

Make maximum contact with all sides of a fastener to reduce slipping. These sockets are also known as torque adapters.

Secure-Grip Tight-Clearance Offset Sockets

The opening shape makes more contact with fasteners for a better grip than standard open-end sockets. Also known as flare-nut or line wrench sockets, they're often used with flared tube fittings and fuel and hydraulic lines.

Socket Adapters and Extensions

Square Drive Size Adapters

Convert from one square drive size to another.

Convertible Square Drive Size Adapters

Push the square drive through the adapter to change size.

Electrical-Insulating Square Drive Size Adapters

These adapters are insulated to protect against accidental contact with live electrical circuits. They are tested to 1,000 volts to meet IEC 60900.

Hex Head Socket Adapter Sets

Attach one of these adapters to a socket to turn it with an open-end or box wrench.

Socket Extensions

Extend your socket's reach.

Nonsparking Socket Extensions

Safely lengthen the reach of your socket while working near flammable vapors and combustible residue.

Electrical-Insulating Socket Extensions

Safely extend your reach in areas where you could accidentally come into contact with live circuits.

Wobble Socket Extensions

The male ends of these extensions are rounded, so they can pivot to use your tool at an angle.

Socket Extension Sets

Keep common extension lengths on hand to reach a variety of spots—just attach them to your socket.

Secure-Hold Socket Extension Sets

Reach a variety of spots with the confidence that your extension won’t disengage.

Flexible Socket Extension Sets

Bend these extensions to reach inconveniently located fasteners. These sets include multiple extension lengths, so you can find the right length to reach around obstructions.

Wobble Socket Extension Sets

Tighten and loosen fasteners in hard-to-reach spots with a variety of extensions that lengthen the reach of your socket.

Flexible Socket Extensions

Bend these socket extensions around obstructions to turn hard-to-reach fasteners.

Secure-Hold Socket Extensions

Lock your socket into these extensions to prevent accidental disengagement.

Adjustable Torque-Limiting Socket Adapters

Set a desired torque within the range.

Factory-Set Torque-Limiting Socket Adapters

Adapters are set to a specific torque and cannot be adjusted.

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.

Hex Shank to Square Drive Adapters

Turn sockets with a bit screwdriver.

Flex Socket Adapters

Pivot the head to access fasteners from an angle.

Fingertip Socket Spinners

Fit these adapters between your wrench and socket to enable finger tightening.

Ratcheting Socket Adapters

Change a standard wrench handle into a ratcheting wrench.

Secure-Hold Socket Adapters

Lock the adapter on your tool and the socket to the adapter to prevent accidental disengagement.

Impact Socket Adapters and Extensions

Impact Square Drive Size Adapters

Convert from one square drive size to another.

Impact Magnetic Square Drive Size Adapters

A magnet holds the socket, making changes quicker.

Impact Socket Extensions

Attach to your socket for a longer reach.

Secure-Hold Impact Socket Extensions

Lock your socket into the extension to prevent accidental disengagement.

Impact Flex Socket Adapters

Pivot the head to access fasteners from an angle.

Impact Torque-Limiting Socket Adapters

Prevent overtightening that can damage fasteners. These adapters spring back slightly when the set torque is reached.

Impact Quick-Change Socket Adapters

Pull the collar to quickly attach and remove sockets.

Impact Socket Extension Sets

Reach a variety of spots by keeping common extension lengths on hand.

Secure-Hold Impact Socket Extension Sets

Also known as positive-locking extensions, these extensions hold sockets place with a ball that only retracts when you pull the collar down. Designed to prevent accidental detachment, they lock to your socket more securely than other extensions.

Continuous-Duty Socket Adapters and Extensions

Hex Shank to Power Socket Square
Drive and Impact Square Drive Adapters

Use sockets with tools that accept hex shanks, such as drills and powered screwdrivers.

Flexible Power Socket Extensions

Bend these extensions around obstructions to access hard-to-reach fasteners.

Continuous-Duty Socket Extensions

First developed for aerospace and automotive assembly processes, these extensions will stand up to your high-volume production and assembly lines.
