Henri, I have noticed that is true at least for BAHCO.

Papaw, actually it was not quite true what I wrote: BAHCO did make series
with right-handed threaded screws, until the eighties, I believe.
Why, I don't know, maybe for export.
From other European brands I have only seen left-handed screws.
Do have all adjustable wrenches in the US right-handed screws?

Somewhere out in my shop I have an adjustable with left hand threads. I have no idea what brand it is or were it is. If I see it in the next while I'll post a pic.

I'm curious.

OK. I was curious too, so I spent some time this afternoon going thru my adjustable wrenches. Out of 189 that I checked I found 3 that have left handed thread. First one is an 8" BAHCO, the second is an 8" CARLL and the 3 rd is an 8" UNIVERSAL. I know I have more packed away but the 189 is probably about 80 to 90 % of what I have. The BACHO is one most of us, I assume, are familiar with. The second one the CARLL was Patented on May 6 1913 Patent number 1060891 and was made some where in New York. The third was created by a guy in Vancouver British Columbia Canada and was patented in Canada with pat number 197760  and also a USA patent number 1305628. Two dates show up for the USA patent June 3 1919 and July22 1919. I took some pictures but I'm having trouble posting them. I'm blaming the camera but I think it's more me than the camera. I'll see if I can get some help with the pics.  Jim.

Now that's curiosity!! Well done, Jim!!!

Gibsontool, thanks for the effort, great job! Nice collection of adjustable wrenches.
I am very curious about the type number of the BAHCO.

Regards
Henri

Did a little more looking today and found a tool box with 18 more adjustables in it. Of the 18 3 are left hand thread, first was another 8" CARLL, same markings as the other one. The second is a 10" IREGA number 77 made in Spain and the third is another BAHCO, this guy is 10"long. Also found another 10" BAHCO with right hand threads. Still trying to sort out the pics so I'll describe the BAHCOS.
The first BAHCO that I posted about yesterday is the 8" and is marked 0167 made in Sweden and has 224 at the tail end ( by the hang hole ), the other left hand one is a 10" marked No 72 and has 2 stars and the number 35 by the hang hole, the other 10" BAHCO ( the right handed one ) is marked 972 AB BAHCO Stockholm and has  113 by the hank hole. The IREGA is marked number 77 Spain.  Jim.
 

Jim, thanks for the search. As for the BAHCO's:
The 10" No.972 (right handed) was made between 1954 and 1968.
The number by the hanging hole is a casting number.

The 10" No. 72 is left handed, the production of this type ended in 1969.
The stars and the number by the hanging hole are casting signs.

The third 8" No. 0167 is probably a bit of a mistake.
There is a No. 0671 that is left handed, made between 1969 and 1983.

I have seen the Spanish IREGA's, but are not popular here.
Seems to be good quality.

Most adjustable wrenches seen here are Swedish or German ones.

As far as I can tell all of my adjustable wrenches have right hand thread adjusters even including my Gedore/Jaguar and Carll wrenches. The first picture is of 4" wrenches,

Henri. You are correct, it is a 0671 and thanks for putting dates to those wrenches.
Don, What length is that Carll you have? Nice bunch of little 4" wrenches
I recently got a new computor and I'm still trying to sort out how to post the pictures. Jim.

Jim,
It's a 6" Carll. I had to find the patent info because I had never heard of Carll before I found it at an estate sale.

Don, very nice collection of 4" adjustable wrenches. I only have three because they are very rare here. Even the BAHCO.
All my larger American adjustable wenches - I only have six - have right-hand adjusters.
The German GEDORE/JAGUAR wrench is specially made for American use.

Henri

Ok. I am the carpenter who does not know what you guys are referring to as far as right hand/left hand threads.Please explain!! Thanks, Lou

Grab a Crescent or other US made adjustable and your hand knows which way to turn the knurl to open or close the wrench. Some European adjustables are opposite.
