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.

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.

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.

These sockets are also known as pin-in-Torx bits.

The short Phillips bit on these sockets fits in spaces that screwdrivers can’t and where height clearance is limited.

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.

Hold fasteners securely in place as you drive them.

With more than double the clearance of standard sockets, these sockets access nuts on extra-long bolts.

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

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

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

Designed to fit on external Torx-Plus fasteners, often found on pickup trucks, these sockets have squared lobes that resist slipping at high torque.

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

These sockets fit the nuts found on water and gas valves.

Slip these slotted sockets onto wing nuts to tighten or loosen them with more force than fingers can apply.

Tighten and loosen fasteners with an external Torx drive.

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.

Pivot the head to access fasteners from an angle.

Tighten or loosen nuts and bolts without damaging the finish.

Extra length allows access to fasteners on long bolts.

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.

Turn 5-point tamper-resistant nuts and bolts often found on water and gas valves.

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

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.

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.

Tighten or loosen hard-to-reach fasteners with the extra-long bits in these socket sets.

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

Suitable for occasional maintenance work, these sets are imported.

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

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

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

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

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

Pivot the head to access fasteners from an angle.

Tighten or loosen nuts and bolts without damaging the finish.

Use one socket to switch between two fastener sizes.

Convert from one square drive size to another.

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

Push the square drive through the adapter to change size.

Extend your socket's reach.

Safely extend your reach in areas where you could accidentally come into contact with live circuits.

Keep common extension lengths on hand to reach a variety of spots—just attach them to your socket.

Tighten and loosen fasteners in hard-to-reach spots with a variety of extensions that lengthen the reach of your socket.

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

Lock the adapter on your tool and the socket to the adapter to prevent accidental disengagement.

Pivot the head to access fasteners from an angle.

Set a desired torque within the range.

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.

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

A magnet holds the socket, making changes quicker.

Attach to your socket for a longer reach.

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.

Pull the collar to quickly attach and remove sockets.

Attach your impact square-drive sockets to power drills, impact drivers, and other tools that accept a hex shank.
