Square Drive Sockets and Ratchet Wrenches

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.

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.

Ratcheting Box-End Tight-Clearance Offset Sockets

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