The toughest bits available, these withstand the shock and twisting force of impact drivers. Designed for screws with a square recess in the head, they are also known as Robertson bits.

Bits have a different size at each end.

The tip is shaped like an eight-pointed star.

While screws with a Square/Phillips combination drive can be turned with either a Square or Phillips bit, these make the best contact so you can apply high torque without slipping and stripping the recess. They are also known as Quadrex bits.

Assortments contain bits with multiple drive styles.

Lock your bit into the adapter to prevent accidental disengagement. These adapters attach to square-drive tools.

Designed to withstand high torque and force, these adapters fit the square drive on impact wrenches. Use with hex-shank bits (also known as insert bits).

A ratchet mechanism turns fasteners more quickly than a standard bit driver. Insert a bit into the shaft and a magnet holds it in place.

An insulated handle and shaft protect against shock from accidental contact with live electrical circuits. These tools are tested to 1,000 volts to meet EN 60900 and IEC 60900.

Choose a handle based on torque and change shafts to use a different size or drive style. Factory-set screwdrivers ensure you reach the same torque every time.

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.

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

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

These sockets are also known as pin-in-hex or pin-in-socket bits.

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

Extra length allows access to fasteners on long bolts.

With a plastic insert, these sockets firmly grip hex nuts and bolts without rounding them or scratching highly polished finishes.

Pivot the head to access fasteners from an angle.

Also known as pipe plug sockets, these sockets have a square shape that provides the best possible grip on square fasteners and prevents rounding.

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

For easy tightening and loosening, these sockets have pins that grip the slotted sides on bearing nuts.

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

Pivot the head to access fasteners from an angle.

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

Extra length allows access to fasteners on long bolts.

Quickly position these sockets on square fasteners.

The square shape provides the best possible grip on square fasteners and prevents rounding.

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

Designed to remove and install dual wheels on trucks and trailers, these sockets have a hex recess for accessing lug nuts and a square recess to turn the threaded shafts found on inner wheels.

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

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

The ball end allows angled entry when you don't have exact alignment between the socket bit and fastener.

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

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

Pivot the head to access fasteners from an angle.

Quickly position these sockets on square fasteners.

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.

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

Pivot the head to access fasteners from an angle.

Convert from one square drive size to another.

Convert from one square drive size to another.

These adapters are insulated to protect against accidental contact with live electrical circuits. They are tested to 1,000 volts to meet IEC 60900.

Safely lengthen the reach of your socket while working near flammable vapors and combustible residue.

Reach a variety of spots with the confidence that your extension won’t disengage.

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.

Bend these socket extensions around obstructions to turn hard-to-reach fasteners.

The male ends of these extensions are rounded, so they can pivot to use your tool at an angle.

Change a standard wrench handle into a ratcheting wrench.

A digital display shows how torque measurements change as you turn the wrench. Set the desired torque and angle—lights and an audible alarm indicate when target has been reached or exceeded.

Adapters are set to a specific torque and cannot be adjusted.

Bend these extensions around obstructions to access hard-to-reach fasteners.

A magnet holds the socket, making changes quicker.

Lock your socket into the extension to prevent accidental disengagement.

Also known as positive-locking extensions, these extensions hold sockets 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.

Prevent overtightening that can damage fasteners. These adapters spring back slightly when the set torque is reached.
