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.

Attach your square-drive sockets to drills, powered screwdrivers, and other tools that accept a hex shank. Not for use with impact tools.

Adapters with a pin style retainer provide a more secure hold than ball detent style because you have to depress the pin to attach or remove the socket. Also called positive locking.

Convert from one square drive size to another. The female side of the adapter attaches to your wrench; the male side to your socket. These adapters have a finish that provides some corrosion resistance. Black-oxide adapters are easy to grip when dirty or wet.

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.

Reach a variety of spots by keeping common extension lengths on hand. To withstand the high torque and force of impact tools without fracturing, these extensions are thicker and flex more than extensions for manual drivers.

Also known as positive-locking extensions, these extensions hold sockets in 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. They’re thicker and less brittle than manual extensions, so they withstand the high torque and force of impact tools. They flex slightly when force is applied, so they’re less likely to break. Each set includes three common extension lengths to tackle a variety of jobs.

Use the pulsing of an air hammer along with the controlled turning of a hand wrench to release stuck fasteners without breaking them. These adapters give you better handling than an impact wrench plus more power than turning just by hand. Attach the square drive to your impact-rated socket and insert the round shank into the chuck of your air hammer. As you hammer, use a wrench to turn the hex portion of the adapter to control the socket. Adapters have a 0.401" round shank that fits the most common air hammers.

First developed for aerospace and automotive assembly processes, these extensions will stand up to your high-volume production and assembly lines. They're hardened to resist wear yet have enough flex to withstand the high torque and force of impact tools without cracking. Use them to lengthen the reach of your impact socket.
