Wrench Heads
Reach nuts obstructed by a fluid line or other barrier with these wrench heads. 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. Also known as crowfoot wrenches.

Secure-Grip Wrench Heads
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.
Hex wrench openings achieve the best possible grip on hex fasteners and prevent rounding.

Box-End Wrench Heads
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.

Ratcheting Wrench Head Sets
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.

90° Elbow Fitting Socket Sets
90° Elbow Fitting
(Not Included)
Turn 90° elbow fittings that are in tight spots with the sockets in these sets. Also known as weatherhead sockets, they have a cut out that encases and tightly grips the fitting, which prevents rounding the corners and edges of the fitting as you tighten and loosen it. They attach directly to your ratchet, so you don’t need to move and reposition them, unlike open-end offset sockets. Only use with hand-driven tools.
