Grip more of your fastener head with these wrench heads. They have a hex or 12-point opening with more surface area than rounded wrench heads, so they make more contact with fasteners for a better hold. Also known as flare-nut crowfoot wrenches or line wrenches, they're often used with flared tube fittings as well as fuel and hydraulic lines. Connect them to your socket extension and ratchet wrench to turn fasteners where clearance is limited from both the top and side. You can also attach one directly to your ratchet wrench to convert it into an open-ended ratcheting wrench.

Attach one of these heads to your square-drive ratchet or torque wrench to extend its reach or to access spaces with limited vertical clearance. Add an extension to get to an obstructed fastener.

When used with a ratchet wrench, it can also help you get more leverage to break a stuck bolt loose. When used with a torque wrench, you can easily calculate your desired torque setting with the precise 2" center-to-center length. Also known as torque adapters.

The box end grips all sides of the fastener to prevent slipping. For use with hand-drive tools only.

Get a strong grip in tight areas, even on fasteners that are rounded or damaged. Open the spring-loaded jaws in these heads to access a fastener like an open-end wrench; the jaws will automatically close when you push against the fastener. The 6-point opening grips hex heads on all sides. Also known as crowfoot wrenches. Attach one to a socket extension to reach obstructed fasteners. With the ratcheting feature, you can turn the fastener without removing and repositioning the wrench head.

Also known as crowfoot wrenches.

Attach one of the heads in these sets to a torque wrench for more leverage to loosen a stubborn fastener. Also known as torque adapters.
