Sockets

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.

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.

8-Point Sockets

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

Universal-Fit Sockets

Turn many sizes of square, hex, and 8-point fasteners with one socket. Place over the fastener and 54 pins move to grip it securely.

Tri-Groove Sockets

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

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.

Slotted Bit Sockets

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.

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.

Bolt-Through Sockets

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

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

Power Sockets

The hex shape grips hex fasteners and prevents rounding.

Fastener-Holding Power Sockets

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

Power Hex Bit Sockets

Use bit sockets as an alternative to a screwdriver or L-key.
