Socket Extensions

Extend your socket's reach.

Electrical-Insulating Socket Extensions

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

Nonsparking Socket Extensions

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

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.

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.

Secure-Hold Socket Extensions

Lock your socket into these extensions to prevent accidental disengagement.

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.

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.

Secure-Hold Socket Adapters

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

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.

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 Torque-Limiting Socket Adapters

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

Impact Flex Socket Adapters

Pivot the head to access fasteners from an angle.

Continuous-Duty Socket Adapters and Extensions

Hex Shank to Power Socket Square
