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

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.

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

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

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

Suitable for occasional maintenance work, these sets are imported.
