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. 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.

Tighten and loosen fasteners in hard-to-reach spots with a variety of extensions that lengthen the reach of your socket. Each extension has a rounded male end that pivots in the socket’s square drive, so you can even make adjustments at awkward angles. Use with hand-drive tools only.

Convert your socket into a flex socket to access fasteners from an angle. Also known as universal joints.

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 are made to withstand the high torque and force of impact tools.

Flex adapters pivot to access fasteners from an angle.

Carry fewer impact sockets—these five reversible impact sockets turn 10 fastener sizes. Flip the socket around to turn a different size. The hex shape grips hex fasteners and prevents stripping. Thicker and with more give than traditional sockets, impact sockets stand up better to the high torque and force of impact tools.

The hex shape grips hex fasteners and prevents rounding. These sockets are made to withstand the high torque and force of impact tools.

Use one socket to switch between two fastener sizes. The spring-loaded innermost wall stays in place for smaller fasteners; push the socket onto a larger fastener and this wall slides out of the way.

With twice as many corners, 12-point sockets grab onto hex-drive fasteners more quickly than 6-point sockets. They also match the external 12-point screws commonly found in heavy duty vehicles such as bulldozers and excavators. Also known as double-hex sockets. These sockets are sturdier and have more give than manual-drive sockets, so they'll withstand the high torque and force of impact tools.

Prevent overtightening that can damage fasteners. These adapters spring back slightly when the set torque is reached. They are made to withstand the high torque and force of impact tools.

Made in the U.S.A., these tools handle the toughest industrial applications, provide the best grip on fasteners, and have a superior finish. The hex shape grips hex fasteners and prevents rounding.

Suitable for occasional maintenance work, these sets are imported. The hex shape grips hex fasteners and prevents rounding.

Pair the sockets in these sets with the bolt-through ratchet wrench to reach nuts at the bottom of a long threaded rod or bolt. The hex shape achieves the best possible grip on hex fasteners to prevent rounding their points. For use with hand-drive tools only.

Suitable for occasional maintenance work, these sets are imported. The 12-point shape quickly positions on hex fasteners.
