Flex Socket Adapters


Convert your socket into a flex socket to access fasteners from an angle. Also known as universal joints.
The finish on these adapters resists corrosion. Chrome-plated adapters have a mirror-like finish and are easy to clean. Black-oxide adapters are easy to grip when dirty or wet. They need to be oiled periodically to maintain their corrosion resistance.

Secure-Hold Flex Socket Adapters


Convert your socket into a flex socket without worrying about the adapter falling off. A locking ball on the adapter grips your socket to prevent it from accidentally disengaging; push the button to release the adapter. Also known as universal joints, the adapter pivots so you can access fasteners from an angle. For use with hand-drive tools only.

Secure-Hold Socket Adapters

Lock the adapter on your tool and the socket to the adapter to prevent accidental disengagement. A set screw keeps the adapter on your tool; pull the collar to lock or release the socket from the adapter.

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.

Flex Impact Socket Extensions

Attach one of these extensions to your impact socket to turn fasteners in hard-to-reach spaces. The flex head pivots to access fasteners from an angle. Made of one integrated extension and flex adapter rather than two pieces, the design lowers the risk of an adapter falling as you reach into your workspace. These extensions are sturdy enough to withstand the high torque and force of impact tools.
These extensions require a locking retainer. Use with an impact wrench that has a pin-style socket retainer, or use a socket retaining ring with tools that have a hole- or hole-and-ring style socket retainer.

Secure-Hold Impact Socket Extension Sets

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.

Impact Flex Socket Adapters
Convert your impact socket into a flex socket to access fasteners from an angle. Also known as universal joints. These adapters are sturdy, so they’ll withstand the high torque and force of impact tools.
Adapters with 50° access angle have two pivot points to reach fasteners at an angle twice as steep as standard adapters.
Adapters that list a compatible retaining ring ID require a locking retainer. Use with an impact wrench that has a pin-style socket retainer, or use a socket retaining ring with tools that have a hole- or hole-and-ring style socket retainer.
