Drivers, Keys, and Bits

L-Keys

Turn fasteners from either end and reach into tight spots.

L-Key Sets

Sets include an assortment of keys. These simple tools turn fasteners from either end and reach into tight spots.

Ball-End L-Keys

When a standard-tip key can't make good contact with the recess, a ball end allows angled entry to turn screws in hard-to-reach places.

Nonsparking L-Keys

Made of beryllium copper that is FM approved, these keys help meet OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present. They turn fasteners from either end and reach into tight spots.

Ball-End Driver Shafts

Create your own tool by attaching these shafts to a handle, or use with socket wrenches and power tools. They have a ball end that allows angled entry to make good contact with the recess when a standard-tip shaft can’t.

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.

6-Point Sockets

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.

Extra-Deep 6-Point Sockets

Extra length allows access to fasteners on long bolts.

6-Point Flex Sockets

Pivot the head to access fasteners from an angle.

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.

Box-End Tight-Clearance Offset Sockets

Make maximum contact with all sides of a fastener to reduce slipping. These sockets are also known as torque adapters.

Ratcheting Box-End Tight-Clearance Offset Sockets

A ratchet mechanism allows you to turn fasteners without removing and repositioning the socket.

Tight-Clearance Offset Sockets

Often used with an extension, these sockets turn fasteners and fittings in obstructed areas that a regular socket can't reach. They are also known as crowfoot wrenches.

Secure-Grip Tight-Clearance Offset Sockets

The opening shape makes more contact with fasteners for a better grip than standard open-end sockets. Also known as flare-nut or line wrench sockets, they're often used with flared tube fittings and fuel and hydraulic lines.

Strut Channel Sockets

Designed to fit inside strut channel, these sockets make it easier to mount the channel than using an extension or additional tools.

Spark Plug Sockets

A rubber insert grips the plug to prevent damage.

Bolt-Through Sockets

Turn nuts on bolts and threaded rod, which pass through these sockets.

Impact Sockets

Impact Hex Bit Sockets

6-Point Impact Sockets

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

6-Point Flex Impact Sockets

Pivot the head to access fasteners from an angle.

Thin-Wall 6-Point Impact Sockets

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

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.

Nonsparking 12-Point Impact Sockets

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

Power Sockets

The hex shape grips hex fasteners and prevents rounding.

Socket Sets

Stubby Hex Bit Socket Sets

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

Premium 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.

Value 6-Point Socket Sets

For high quality at a lower price, choose these U.S.A.-made sets.

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.

Economy 12-Point Socket Sets

Suitable for occasional maintenance work, these sets are imported.

Premium 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.

Value 12-Point Socket Sets

For high quality at a lower price, choose these U.S.A.-made sets.

12-Point Flex Socket Sets

Pivot the head to access fasteners from an angle.

Bolt-Through Socket Sets

Turn nuts on bolts and threaded rod, which pass through these sockets.

Box-End Tight-Clearance Offset Socket Sets

Make maximum contact on all sides of a fastener to reduce slipping. These sockets are also known as torque adapters.

Ratcheting Box-End Tight-Clearance Offset Socket Sets

A ratchet mechanism allows you to turn fasteners without removing and repositioning the socket.

Tight-Clearance Offset Socket Sets

Often used with an extension, these sockets turn fasteners and fittings in obstructed areas that a regular socket can't reach. They are also known as crowfoot wrenches.

Secure-Grip Tight-Clearance Offset Socket Sets

Impact Hex Bit Socket Sets

Use these sockets as an alternative to a screwdriver or L-key. They are made to withstand the high torque and force of impact tools.

6-Point Flex Impact Socket Sets

Pivot the head to access fasteners from an angle.

6-Point Impact Socket Sets

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

Open-End Wrenches

Tight-Clearance Open-End Wrenches

The slim head fits into tight spaces and around thin fasteners.

Multi-Size Open-End Wrenches

Also known as alligator wrenches and water-meter nut wrenches, the V-shaped head fits multiple hex fastener sizes.

Tapered-Handle Open-End Wrenches

Also known as spud, structural, and construction wrenches, use the pointed end of the handle to align bolt holes during assembly.

Deep-Offset Tapered-Handle Open-End Wrenches

The head is offset 45° to provide additional clearance when reaching over obstructions.

Tight-Clearance Open-End Wrench Sets

Fit the narrow head into tight spaces and around thin fasteners.

Box Wrenches

Deep-Offset Ratcheting Box Wrenches

The offset head gives you additional clearance to turn hard-to-reach fasteners.

Snap-Open Ratcheting Box Wrenches

Open the jaws to fit around a fastener like an open-end wrench; close the jaws and the wrench acts like a ratcheting box wrench.

Ratcheting Box Wrenches

A ratchet mechanism allows you to turn fasteners in tight spaces without removing and repositioning the wrench.
