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.

Extended-Reach Hex Bit Sockets

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

Stubby Hex Bit Sockets

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

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.

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.
