Sockets

6-Point Sockets

The hex shape achieves the best possible grip on hex fasteners to prevent rounding their points.

Nonsparking 6-Point Sockets

Made of aluminum-bronze, these sockets satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present.

Stubby 6-Point Sockets

These short sockets fit spaces where height clearance is limited.

6-Point Flex Sockets

Pivot the head to access fasteners from an angle.

Fastener-Holding 6-Point Sockets

Hold fasteners securely in place as you drive them.

Extended 6-Point Flex Sockets

Eliminate the risk of your socket falling while reaching into your workspace with these flex sockets that have an integrated extension.

Bolt-Through 6-Point Sockets

Pair these sockets with a bolt-through ratchet wrench to reach nuts at the bottom of a long threaded rod or bolt which can pass through the socket and the head of the wrench.

12-Point Sockets

Electrical-Insulating 12-Point Sockets

Insulated to protect against accidental contact with live electrical circuits, these sockets are tested to 1,000 volts to meet IEC 60900.

12-Point Flex Sockets

Pivot the head to access fasteners from an angle.

8-Point Sockets

Quickly position these sockets on square and external 8-point fasteners.

Tri-Groove Sockets

Grip the indentations around the outside of tri-groove fasteners.

Universal-Fit Sockets

Turn multiple shapes and sizes of fasteners with a single socket.

Bit Sockets

Hex Bit Sockets

Electrical-Insulating Hex Bit Sockets

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

Stubby Hex Bit Sockets

The short bit on these sockets fits in spaces where height clearance is limited.

Extended-Reach Hex Bit Sockets

Extra-long bits allow access to hard-to-reach fasteners.

Dual-Drive Hex Bit Sockets

When vertical space is tight or you need an extra twist on your socket, use these dual drive hex bit sockets. They work with a standard square drive tool and a box or open end wrench.

Slotted Bit Sockets

Wrench Heads

Reach nuts obstructed by a fluid line or other barrier with these wrench heads.

Secure-Grip Wrench Heads

Grip more of your fastener head with these wrench heads.

Box-End Wrench Heads

Attach one of these heads to your square-drive ratchet or torque wrench to extend its reach or to access spaces with limited vertical clearance.

Impact Sockets

6-Point Impact Sockets

Achieve the best possible grip on hex fasteners and prevent rounding.

Fastener-Holding 6-Point Impact Sockets

A magnet holds the fastener securely enough to drive self-tapping screws.

Thin-Wall 6-Point Impact Sockets

With a smaller OD than standard sockets, these fit between tightly spaced fasteners.

6-Point Flex Impact Sockets

Pivot the head to access fasteners from an angle.

Extra-Deep 6-Point Impact Sockets

Extra length allows access to fasteners on long bolts.

12-Point Impact Sockets

The 12-point shape quickly positions on hex fasteners.

8-Point Impact Sockets

Quickly position these sockets on square fasteners.

Impact Hex Bit Sockets

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

Stubby Impact Hex Bit Sockets

The short bit on these sockets fits in spaces where height clearance is limited.

Extended-Reach Impact Hex Bit Sockets

Extra-long bits help you access hard-to-reach fasteners.

Replacement Bits for Hex Bit Sockets

Switch out worn or damaged bits instead of replacing your entire bit socket.

Continuous-Duty Sockets

Continuous-Duty 6-Point Sockets

These sockets are designed to tolerate continuous use with power tools and impact tools in high-volume production and assembly.

Continuous-Duty Fastener-Holding 6-Point Sockets

A magnet holds the fastener securely enough to drive self-tapping screws.

Continuous-Duty Hex Bit Sockets

These sockets are designed to tolerate continuous use with power tools and impact tools in high-volume production and assembly.

Socket Sets

6-Point Socket Sets

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

Economy 6-Point Socket Sets

Suitable for occasional maintenance work, these sets are imported.

Bolt-Through 6-Point Socket Sets

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.

Nonsparking 6-Point Socket Sets

Made of aluminum-bronze, these sockets satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present.

6-Point Flex Socket Sets

Access 6-point nuts and bolts in tight and awkward spaces—the heads on these sockets pivot.

Fastener-Holding 6-Point Socket Sets

Two spring-loaded balls inside these sockets firmly hold nuts and bolts in place as you turn them, including nonmagnetic fasteners like stainless steel screws.

12-Point Socket Sets

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

Economy 12-Point Socket Sets

Suitable for occasional maintenance work, these sets are imported.

12-Point Flex Socket Sets

Pivot the head to access fasteners from an angle.

Electrical-Insulating 12-Point Socket Sets

These sets organize what you need when working around live electrical circuits.

8-Point Socket Sets

With twice as many corners, 8-point sockets grab onto square-drive screws and nuts more quickly than 4-point sockets.

90° Elbow Fitting Socket Sets

Turn 90° elbow fittings that are in tight spots with the sockets in these sets.

Hex Bit Socket Sets

Extended-Reach Hex Bit Socket Sets

Extra-long bits allow access to hard-to-reach fasteners.

Stubby Hex Bit Socket Sets

The short bit on these sockets fits in spaces where height clearance is limited.

Dual-Drive Hex Bit Socket Sets

In addition to a standard square drive, the sockets in these sets have a hex-shaped base so you can use a ratchet wrench along with an open-end or box wrench for additional leverage.

Wrench Head Sets

Box-End Wrench Head Sets

Attach one of the heads in these sets to a torque wrench for more leverage to loosen a stubborn fastener.

Wrench Head Sets

Reach nuts obstructed by a fluid line or other barrier with the wrench heads in these sets.

Ratcheting Wrench Head Sets

Connect one of the heads in these sets to a socket extension to reach an obstructed fastener, then turn the fastener without removing and repositioning the wrench head.
