Socket Extensions
Attach these extensions to your socket for a longer reach. Use with hand-drive tools only.
Chrome-plated extensions have a smooth, shiny surface that resists corrosion and is easy to clean.
Black-oxide extensions aren’t as smooth as chrome-plated extensions, so they’re easier to grip when dirty or wet. Oil them periodically to maintain their corrosion resistance.

Electrical-Insulating Socket Extensions
Safely extend your reach in areas where you could accidentally come into contact with live circuits. These extensions are tested to 1,000 volts to meet IEC 60900 and ASTM F1505 standards. This means you can use them for working on or near live parts. Use them with hand-drive tools only.

Wobble Socket Extensions
The male ends of these extensions are rounded, so they can pivot to use your tool at an angle. Use with hand-driven tools only.
For technical drawings and 3-D models, click on a part number.
Secure-Hold Socket Extensions
Lock your socket into these extensions to prevent accidental disengagement. Also known as positive-locking extensions, they have a ball that secures your socket and only retracts when you pull the collar back. This creates a stronger hold than standard extensions. Use them with hand-drive tools only.
Flexible Socket Extensions
Bend these socket extensions around obstructions to turn hard-to-reach fasteners. They’re best for light duty adjustments because they can’t apply as much torque as standard socket extensions. Use them with hand-drive tools only.

Adjustable Torque-Limiting Socket Adapters
To set torque, remove the snap ring and locking plate and adjust the nut. When the torque setting is reached, the adapter clicks and releases. These tools let you accurately measure or limit the torque you apply to prevent overtightening and damaging fasteners.
Use clockwise and counterclockwise adapters to tighten fasteners in both directions. You’ll need to change tools to loosen the fasteners.
Use clockwise adapters to tighten fasteners in the clockwise direction as well as loosen them in the counterclockwise direction. There’s no need to change tools.

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.
Note: The accuracy ratings do not apply to the lower 10% of the torque range.

Secure-Hold Impact Socket Extensions
Lock your socket into the extension to prevent accidental disengagement. Locked in place by a ball that retracts when the collar is pulled (also called positive locking), these sockets hold more securely than our standard extensions. These extensions are thicker than standard extensions, and also have enough give to flex under high force without breaking. This makes them a good choice for use with impact tools.

Secure-Hold Bit Adapters for Ratchet Wrenches
Lock your bit into the adapter to prevent accidental disengagement. These adapters fit square-drive tools and accept hex-shank screwdriver bits. They have nonmagnetic bit holders, so they won’t attract loose metal parts and shavings.
To secure a bit in adapters with quick-change chuck, pull back on the chuck to insert the bit and then push it forward to lock the bit place.
To secure a bit in twist-lock adapters, tighten the knurled end.
