Such an annoying size skip. I like to collect (and use) older combination wrenches. It seems every set skips 1-3/16”. It is a size I actually use. It was common on 30-60 series John Deere row crop tractors (John Deere sells decent wrenches, they do not make a 1-3/16”…..).

So I only have Snap On in 1-3/16”. Did PROTO ever sell an 1-3/16” combination wrench? Any other companies? What brands do you guys have in that size?

A 1-3/16 is not shown in the 1953 or 1967 Proto catalogs. What is interesting is that the part numbers skip from 1236 (1-1/8) to 1240 (1-1/4). In theory a 1238 should be 1-3/16

^ I checked ebay listings. Only thing I could find in a 1-3/16" combo was either Snap-on (about $85) or made-in-China.

Looking at Indestro catalogs, it appears they never made one. Or Thorsen, from what I could find.

Is the OPEN END of the Model T Ford spark plug wrench a 1-3/16" opening?

This has come up on the Plomb board before as to what the specific need was for in the WW2 era Navy contract that required a 1 3/16" combo as Plomb didn't include one in their standard line.... maybe a Navy or Naval Air specific thread could get the right person to weigh in with an answer but for now here's their wrench. I have another 1 3/16" Plomb like this somewhere and beside the stamped NAF ID it has a local unit Navy ID scrawled on it as well.

As far as I know the Model T plug wrench is 15/16. I can dbl check when I get home later on.

According to the chart in the back of the Plomb 18A catalog, the only fastener that used a 1-3/16" head was a Manufacturer's Standard in 3/4". That opening was not a standard size, but was a "Standard" size!

Nice picking, Mr. X!

That's cool. I would love to find one of those. Probably not very common.

I finally found an Armstrong to complete my set. It is full polish and not dull like the rest, but my OCD has been okay with that so far.

Only one fastener standard used that size, and it was not a popular standard. It is not a size that one would expect to need a wrench for.

I have only encountered one application that has a 1-3/16" hex fastener, and that is a lug nut on a road grader. I believe that some trucks used the same lug nuts. A combination wrench would not be useful on this application, because access is blocked by the rim and the projecting hub.

Funny that this post would come along now... we were working on a John Deere planter on Monday, and the wrench needed for a particular job seemed to be 1-3/16". A big Crescent wrench was used instead.

Something interesting with 1-3/16 stuff, sockets are rare too.

1/2 drive is understandable, I have 1-1/2 and 1-5/16(actually haven't seen another 1-5/16 socket before) sockets but both seem a bit much. You can still find 1-3/16 for sell but only 12 point as far as I've seen.

3/4 drive it's actually a common size, comes in the box sets. However in almost every used set I've seen it's always missing along with 1 inch. I'd have to imagine 1-3/16 is common on something because those sockets wouldn't be missing just for weight reduction.

Looking at old and newer Stahlwille catalogs no 1 3/16” in either open ends or combos.

That leaves options being sockets or box end wrenches only.

I found two more applications for 1-3/16" fasteners. I had to remove a declutch valve from my Case 850 bulldozer, and found that the body is 1-3/16" hex! I used a 1-1/4" 6-point socket to remove it, and dug out my 1-3/16" 3/4 drive socket to reinstall it.

I was looking at the Plomb 15A catalog from 1936, and in it they call out a 1-3/16" socket for 1932 Chevrolet rear axles. I found one of these sockets in a group of Plomb parts I bought today.

Older Standard Wrench sizes for S.A.E. and U.S.S. were:
1/2" = 3/4, 7/8
5/8” = 15/16, 1_1/16
3/4" = 1_1/8, 1_1/4

1_3/16 was not commonly encountered.
Looks like most wrench makers catered to users rather than collectors and stuck with the popular sizes.

All my big wrenches are mostly Wright and a 1 3/16” is in the arsenal. Did I mention that can be found cheap?

I’ve got both Proto and SnapOn in 1-3/16….. It is a fairly common size for the packing follower adjustment on big pumps.

I use them fairly regularly. I don't collect them to look at, I collect them to use.

I have not seen a Wright for cheap (or at all) in 1-3/16", but would buy one if I saw it.

eBay is a good source for Wright goodness, A quick google shows a 1 3/16” Wright wrench ranging anywhere from $37-$47 from various Industrial supply houses.

You didn't define "older" (and I have no idea when "30-60 series John Deere row crop tractors" were made), but if you look in any Machinery's Handbook before 1949 (which is about as late as I go in interest), you will not find a nut or bolt with an across-the-flats diameter of 1-3/16" in any of the tables (BSW, U.S.S., Am. Std. or S.A.E.). Not really a "skip", per se, then, by wrench makers who weren't offering it, and just the opposite for those who were. It would be a special, an application where a mfgr was using a non-standard fastener. As Jock and leg17 alluded to. Those may or may not show up in vintage catalogs in your "older" "30-60 series" timeframe, but that would be one way to try to identify who made them.
