Sort of a love-hate relationship here at GJ it seems, but there are decent solutions as well.

The one everyone loves to hate seems to be the plain open end with the notch in it. (Top in the pic) not useful for anything close to high torque, but seems to work for light use, within the 60 deg limits of the hex nut. Smaller swing angles than than that not too useful.

I have a few Imperial hinged jaw "opening" box wrenches that can give you the access an open end gives you, with the full enclosure of a box. well made, and strong, enough, despite the stamped shell handle. its weakness is where the jaws hinge, but does an ice job nonetheless. this gets things down to 15 deg, swing, and only a little limiting for access around the bolt or nut head. I've got two in the pic; one open and one closed. I wish I had a full set of these...

My next example is a Heller Bros. Masterwrench; by far the best from a torque perspective, ease of use and strength of wrench. You also don't need but two or three of these to cover many sizes, and its SAE/metric agnostic.

Its issue is 60 degree swing, like the open end with the notch, and head access space needed, similar to a crescent, (but far less likely to round something off than a crescent or even a regular open end. the harder you pull the tighter it grips. I keep one of these in my camp gear for doing the propane connections. I keep the handle painted florescent orange and a wire hook on the end eye so I can hang it handy in camp.


Primary drawback is availability: This was made in the 20's through about post WWII era I believe.

Of the three I'll go for the Masterwrench first as long as the access is there. the Imperials next and the notched jaw last, and only for light use.

How about everyone else - any other solutions for an open end ratcheting tool? Likes or dislikes?

i think the middle one looks pretty handy, don't like the top one, used them before and could never get used to them

I think somebody, Proto maybe, sells something like the second one as a ratcheting flarenut or something like that.

I have a set of metric Craftsmans like the top one that my in-laws gave me for Christmas about 20 years ago. I think I've only used the pseudo-ratcheting feature two or three times.

I don't care for them, as you typically can't get into tight spots or get higher torque. But as a tool junkie I like the pics you posted, interesting to see the designs and how old some of them are.

IIRC, the top one was patented by Thorsen sometime in the '50s. I've seen one of those, but many more of the Cman Father's Day Specials. Even accidentally bought one once.

Don't care for which? Any of them? I posted three distinctly different types. :dunno:

It is intended as a ratcheting flair wrench, but it can be used on any fastener, which would be clumsy with a std Flair...

I find ratcheting open-ended wrenches fascinating as an engineering problem and even if they aren't practical for very many use cases, I'm always curious to see a new design.

That Masterench looks like its design was "borrowed" by Apex for its Craftsman/Crescent "clench wrenches" (adjustable ratcheting wrenches are another extensive category with some overlap).

Link? I'm not remembering that one.

I really like the look of that master wrench. I've been hoping to find one since you posted a pic a few weeks ago in the garage sale thread. Alas, no luck yet.

I bought one (SRXM13)for a limited access situation. Then I bought a few more.

Still looking for an SRXM19.

I also have a few Cam-Loc wrenches. Those are nice and handy and I'll have to fill in my size gaps some time.

Funny how the designs grey the idea of "open end". :)

I was thinking about this from an engineer stand point.

What if someone made a head like this? It would be a semi flare nut end? And rotate? What would stop someone from adding the necessary gears and foots etc...to make it a ratchet design? The head or "open cut" would only be open to slide a nut or bolt into at at 1 position but after that you would be free to start rotating it. And it wouldn't slip off.

Does this make sense or have I had too many?

(Yes, this is a fishing rod holder, it's the thought I'm going for not the execution) (the bottom peice)

Don't ask.
The ones I've tried seem to be a bit quirky and didn't work well. The open end ones are just another gimmick to address a problem that doesn't exist.
The ratcheting flare nut wrenches (like the Imperials shown) worked OK for breaking the nut loose. But after that there wasn't enough tension on the threads to operate the ratcheting mechanism.

I have a full set of the armstrong ones that are similar to the #1 style. A little different take on it though. The don't need much depth clearance either which would limit the use of the other styles when the nut is next to an obstruction.

I use them when you only have access to the nut with an open end and you need the wrench to back the nut all the way off. I use them alot for fan clutches.

Yep. Bonney made them. I have a few.

Breaking them loose is always the issue though, isn't it? After that, a std open end or even the ratchet open end will do the turning just fine.

Stratman, those look a lot like the one that Chevy EFI posted.

Bonneyman, I've seen those posted a few times, never seen on in the wild. was Bonney in Utica, or did Utica make those?

One or two different companies still manufacture the Heller Masterench style wrenches, although not in the USA. Rothenberger, the German pipe tool manufacturer, offered them in 6", 8" 10", and 12" sizes. The last catalog I checked from Rothenberger didn't list them so they may have stopped, but I'm not sure that Rothenberger was actually manufacturing the wrenches themselves.

One of the Japanese tool companies was also selling Masterench style wrenches. I orget which one, but it was probably one with an unsearchable name on Google like Top, or Hit, or Super. The wrenches were offered in the same sizes as the Rothenberger ones, so the Japanese company may be the actual manufacturer. The design of the wrenches is pretty much a direct copy of the Heller wrenches.

Ridgid also manufactures Pipe wrenches called Rapidgrip wrenches that use a similar principal, but the jaws are wider for plumbing aplications. There are 10" and 14" cast iron handled versions, and 14" and 18" aluminum handled versions.

https://www.ridgid.com/us/en/rapidgrip-wrench

https://www.ridgid.com/us/en/aluminum-rapidgrip-wrench

It looks like Rothenberger may still offer the Heller type wrenches.

http://www.rothenberger-usa.com/en/products/-/131-one-handed-type-r-/

And it looks like Top Kogyo is the Japanese company I was thinking of. The wrenches are available in the same sizes as the Rothenberger ones.

Bonney and Utica (as well as Herbrand I believe) were bought up by Kelsy-Hayes toward the end of the 50's. Since they did brake systems, the Cam-Locs really were a perfect corporate fit. And I believe GM had a connection, too, as the ratcheting flares I have are marked "G.M." Probably for their brakes and/or AC division.
I have several flare wrenches (not necessarily Cam-Loc's) from that time period that have different names forged on them. So the tooling was probably shared among the sister companies. This is prior to 1967 - when Triangle Tools bought them all out.

Neophyte, Heller made pipe wrenches with teeth as well. I didn't roll them out in this thread as its about open end solutions, but interesting that they are still made by someone, even if only in the pipe versions. (Yeah, I'm dissing on that robogrip version... :evil: )

I work on a lot of cars and they're all too big, just about everything is a tight spot on cars. I love the designs though, they don't work for most of what I do due to tight spots. I would think to have these on the tractor and use them on a piece of three point equipment to limp something home would be useful.

I thought several times about the flare nut ratchet wrenches mentioned by NKlamerus would be nice to have. For high torque, I use a 6pt socket, or regular combo wrench. If the torque isn't high, I love the ratchet wrenches! I have regular, stubby, and flex head in SAE and Metric. I love them!

Sorry, I actually didn't realize that the heller didn't have teeth and was meant for hex nuts. As far as the laminated craftsman versions, I think I just keep blanking them from my brain like a memory I'm trying to suppress.

Will the open end ratcheting wrench open a capped beverage? That may be worth the price of admission alone.
Twist cap?

One like the SRXM13 I posted, probably not.

A Cam-Loc the right size, probably yes.

A pipe-wrench style as neophyte posted, you bet.

Thanks JC; yes very reminiscent. Not sure what nimrod decided to have that sucker fold in the direction of the pull but that looks like an accident waiting to happen... and more "robogrip" stamped steel construction.. :dunno:

Here is a couple that I picked up somewhere back in my days of working for a property management company. These have fixed handles, though they still have the stamped steel plate construction.

I bought a set of the Craftsman ones...thought they looked cool and useful for cooler lines. They sat and took up space until I threw them in my box of weld and cut wrenches. I used them a couple times and really didn't like them.

I ordered a Snap-On SRXM17 in hopes of using the open end as a bottle opener. I don't think I would ever use it to torque a fastener. I worry that it would slip easily. As it is the Snap-On Flank Plus Drive open ends mark up screw heads.

I have an old 10-inch Masterwrench, Outlaw, but mine has toothed jaws like neophyte's Top Kogyo reference. I wish it was your smooth jaw version -- I'd use it more.

I have a set of the CM RP cutout jaw versions around here as well, but I've never liked that design and I don't use them.

Tony, That looks a lot like a cross between the Imperials and the Heller Masterwrench. Looks beefy enough, and they make that huge 2-4 version.
