Self-Adjusting Ratcheting Box Wrench Head Sets


Wrench and Socket Extension Not Included

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.

Sure Grip Wrench Head Sets


Wrench and Socket Extension Not Included

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 a 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.

Ratcheting Wrench Head Sets


Wrench and Socket Extension Not Included

Connect one of the heads in these sets to a socket extension to reach an obstructed fastener, then turn the fastener without removing and repositioning the wrench head. These also work well where clearance is limited from both the top and side. Alternatively, attach a head directly to a wrench handle to convert it into an open-ended ratcheting wrench. Also known as crowfoot wrenches.

Open-End 6-Point Socket Sets

The sockets in these sets have a cutout and extra length so you can reach and twist nuts without having to disconnect your line. Connect them to a ratchet wrench to turn nuts around a wired sensor, fuel line, or hose without having to remove and reposition your wrench. The hex shape achieves the best possible grip on hex fasteners to prevent rounding their points. For use with hand-drive tools only.

Open-End 6-Point Sockets

Slide the open side of these sockets over a tube or hose to adjust a nut that’s already installed. You can turn them with ratchets, so they’re easier to use than open-end wrench heads—no need to pull the socket off the nut and reposition. The hex shape provides the best possible grip on hex fasteners and prevents rounding. Only use with hand-driven tools.
