These crowfoot wrenches caught my eye as I was walking through the local Sears — at first I thought they were the same old tool in a new package, but a second look showed ’em to be a new-to-me flare-nut version.  Attached to an extension, crowfoot wrenches have often helped me get to out-of-reach fasteners, and these flare-nut versions should do the same trick for those hard-to-reach hydraulic fittings.

The wrenches come in both metric and standard ten-piece sets — the standard sets are in sizes 3/8″ to 1″, and the metric are in sizes 10 to 19mm.  The fully polished wrenches have the look of Sears’ professional line of tools.

Craftsman’s Crowfoot Flare Nut Wrenches sell for about $80 per set.

    Okay dumb question I know but how do they work?

    They are an attachment for a 3/8 ratchet handle.

    I imagine I’ll be quickly corrected by my peers out there, but I don’t see where these would offer any easier access to fasteners than a standard issue flare nut wrench. From my experience with regular crow’s feet, the 3/8 extension bar causes as much obstruction as it cures. And $160 for both sets is pretty steep. Gearwrench makes a flex head flare nut set. They’re not cheap either, but seems to me they’d be more versatile.

    I dunno. I’ve got a set of flare nut crows feet, and have had to use them just once…I’m thinking it was on the hydraulic line to the clutch slave cylinder on an old SAAB. Were they worth the cash? That day I thought they were…

    They work really well in spaces where you don’t have room to swing a regular line wrench. Power steering hose ends are a common use spot for flare crowfeet. As with any Craftsman tool, wait for a sale to buy it. I picked mine up last November when they first came out before Christmas and got them for half off.

    We like the ratcheting flare wrencehes made by Proto. Our older sets were a bit beefier and USA-made – but our new Armstrong sets get the job (plumbing) done:

    these will get you out of a tight spot … i use mine for power steering hoses… for loosening the adjusting nuts on steering boxes.. usually with a long long extension.. with another with a tee handle on top to adjust the set screw..

    transmission lines.. with a backing wrench to prevent the fitting the line is screwed into from backing out and making a candy cane of the tube…

    there is also a trick.. if it does not loosen the fastener right away.. tighten it SLIGHTLY.. just enough to break it loose.. this also works for regular flair nut wrenches…

    one thing.. there are various sizes of fitting on cars.. so you might need both sae and metric… depending on the age of the cars you work on…

    18mm is used on a lot of ps hose ends.. 16mm is really really close to 5/8 another popular size… as is 15mm…

    i do use these with ball end extensions.. sometimes with locking end extensions.. sometimes with a ratchet on the top… other times with a breaker bar.. and once in a while with a tee handle…

    on some applications like jeep grand cherokees.. you can adjust the steering box in under 2 minutes… without taking anything off..

    i had snap on and mac versions along with a set from HF… they occupy their own small drawer in my top chest…

    These are made by SK and are a lot less expensive than SK’s own brand, not to mention an easier exchange at Sears.

    For those unfamiliar with the term, these are a type of ‘line wrench’ because they are typically used to engage fittings on hydraulic lines and the like wher a socket or box wrench cannot access the fastener because the line is in the way. Definitely better than an open end wrench because of better contact.
