to Square Drive Adapters

Insulated to protect against accidental contact with live electrical circuits, these adapters are tested to 1,000 volts to meet IEC 60900 and ASTM F1505 standards.

Dual-Drive Socket Adapter Sets

Attach a socket to one of these adapters—the base has a hex shape so you can use a ratchet wrench along with an open-end or box wrench for additional leverage.

Secure-Hold Socket Adapters

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

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.

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

Socket Extension Sets

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

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.

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.

Wobble Socket Extensions

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

Secure-Hold Socket Extensions

Lock your socket into these extensions to prevent accidental disengagement.

Flexible Socket Extensions

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

Ratcheting Socket Adapters

Change a standard wrench handle into a ratcheting wrench.

Flex Socket Adapters

Convert your socket into a flex socket to access fasteners from an angle.

Flex Socket Adapter Sets

Convert your socket into a flex socket to access fasteners from an angle.

Secure-Hold Flex Socket Adapters

Convert your socket into a flex socket without worrying about the adapter falling off.

Finger-Tightening Socket Adapters

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

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.

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.

Square Drive Adapters for Box Wrenches

Attach one of these adapters to a ratcheting box wrench to convert it to a ratcheting socket wrench.

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 Square Drive Adapter Sets for Power Tools

Attach your impact square-drive sockets to power drills, impact drivers, and other tools that accept a hex shank.

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.

Flex Impact Socket Extensions

Attach one of these extensions to your impact socket to turn fasteners in hard-to-reach spaces.

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.

Impact Quick-Change Socket Adapters

Pull the collar to quickly attach and remove sockets.

Impact Flex Socket Adapters

Convert your impact socket into a flex socket to access fasteners from an angle.

Impact Square Drive Adapters for Power Tools

Attach your impact square-drive sockets to power drills, impact drivers, and other tools that accept a hex shank.

Impact Flex Socket Adapter Sets

Convert your impact socket into a flex socket to access fasteners from an angle.

Impact Square Drive Adapters for Air Hammers

Use the pulsing of an air hammer along with the controlled turning of a hand wrench to release stuck fasteners without breaking them.

Impact Torque-Limiting Socket Adapters

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

Impact Spline Drive to Square Drive Adapters

Attach your square-drive impact socket to a spline-drive impact wrench.

Continuous-Duty Socket Adapters and Extensions

Continuous-Duty Square Drive Size Adapters

These adapters, which convert from one square drive size to another, were designed to tolerate continuous use with impact tools in high-volume production and assembly.

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.

Continuous-Duty Square Drive
Adapters for Power Tools

Use these adapters to connect sockets to impact wrenches and other power tools—they’re designed to tolerate continuous use in high-volume production and assembly.

Flexible Power Socket Extensions

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

Socket Sets

Reversible 6-Point Impact Socket Sets

Carry fewer impact sockets—these five reversible impact sockets turn 10 fastener sizes. Flip the socket around to turn a different size.

Dual-Size 12-Point Impact Socket Sets

Use one socket to switch between two fastener sizes.

Impact Square Drive Size Adapter Sets

Convert from one square drive size to another.

Impact Torque-Limiting Socket Adapter Sets
