1-3/16” socket and wrench size

[ForrestT]

How common is 1-3/16”? Do any of you use it often? If so, on what? I do not have that size in a socket or wrench and wondered if it’s used. Thanks.

A good substitute for 30 mm. That's the front axle nut on a modern Ducati.

 

[MadMark]

1-3/16" = 30 mm, good for front wheel drive axles.

1.188" * 25.4 mm/in = 30.16 mm

Mike just beat me to it.

 

[BlakeTheCarGuy]

Yep when I split my 30mm 12 point axle nut on a Toyota a few years ago had to go dig out the 1 3/16 socket never thought I would use it I was wrong

I had the same question some time ago when considering to add a Snap On 1944 socket to my set which I am still working on. Not a part of the set, but bought one since it appeared not common and the price was not bad...

My set of SK combination wrenches skips that size. My obsession wanted to fill the void until I saw the price. I doubt I would ever use it.

 

[xela456]

Ive had one in a proto set for about 8 years now. I've only ever used it on metric bolts and not since I got my SK metric impact set! I could probably stop carrying it!

I first read the interchangeability with 30mm in shop manual for VW Rabbit front wheel bolts. Rabbits for Dummies, I think it was, chuckle. While 30mm is very common on metric machines, I have never run across 1 3/16" on either the imperial or the Whitworth machinery.

 

[Dave455]

Going from memory, 1 1/8 is a standard size for a 3/4 bolt. 1 1/16 and 1 1/4 are standards too, for heavy bolts, but I don’t think 1 3/16 features. Maybe on the old National (pre unified) or USS standards? Maybe some pipe fittings. Certainly some “specials”.

If I had one I wouldn’t ditch it, but I probably wouldn’t rush out and buy one either.

I have wrenches from 1/4 to 1 1/4 to hand, but skipping 1 inch and 1 3/16. I can’t ever remember needing these sizes.

If I needed to use something on a 30mm I’d use a 30mm wrench. That is a common size.

1" shows up the odd time. 1 1/4" head size is the head size of 3/4" structural iron bolts, so I've seen them in industrial plants . Most often I've hooked it on a 1 1/8" to get more leverage.

 

[Wrench97]

Buddy of mine took an extra I had to use on his Ammo reloader.
Past that I used them on steering box mounting bolts and pitman arm pinch bolts on Volvo trucks(actually 30mm).

 

[NoahG]

I used a 1-3/16" on some pipe reducers, thats about it.

 

[bobcatdan]

John Deere loved 1 3/16" to hold their tractors together. After switching to metric, now covered in 30 mm bolt heads.

 

[Lassen Forge]

Y'alls too fast for li'l ol' me

I was gonna say Deere equipment and front axle nuts but ya beat me to it. Bah!

I have a bunch of bike tools, mostly freewheel removers, that have 1" hex heads on them. Pretty sure I used to use it when I worked on my dad's Ford 8n, too.

You obviously never had a Volvo with a cast iron (red) block engine from the 60s to the 90s - they all had a UNC 3/4" oil drain plug that took a 1" wrench.

Just read this through and I will summarize to save anyone who just wants the Cliff Notes.........1 3/16 can substitute for a 30mm. if you are not going to remove an axle nut or work on a John Deer than you will likely never have a need to use it.

 

[KnurledNut]

I picked up a 1-1/8 four way angle wrench that was enlarged to this size. I figured it was used on heavy equipment.

Wait until you pull the lugs off an early 80's dodge neon that lost it's chrome lug nut covers - that takes an 18.5 MM socket - 18 won't fit, 19 (which is what fits ith the covers) will strip the edges of the bolt. i went through absolute **** finding someone who could order one for me - when I asked, they said "Oh, you own a Dodge neon"...

Pieces of literal s#!+...

Cat too- very common size for those brands.

 

[Mgdoug3]

The AC disconnect lines under the cab for John Deere Soundguard cabs also use 1 3/16" wrench.

 

[SDF]

The Embraer 145 uses a 1-3/16" socket/service wrench for the fuel pump cannon plug receptacles.

Make sense Cat would. I have noticed they like odd sizes. My 16mm wrenches get a work out on Cats. Now that you say it, I d remember 30 mm on Cats.

I wonder if it comes from Cat’s earlier metric machines coming from Japan. I know 13, 16, 18, 15/16, 30 and 1 7/16 are the most common bolt sizes I deal with daily. It’s a little annoying because cheaper tools tend to leave out 16 and 18s in the sets so I always have to check before buying.

It’s also a pain when hardware has been replaced with aftermarket and you have to go fetch the rarely used 17mm socket to get that one bolt out

 

[MadMark]

5/8" can substitute for 16 mm

And 15/16 is close to 24 mm

I feel like 17mm is one I use a lot, the collets on our palm routers and the bolt on the abrasive chop saw are the two that immediately come to mind. I keep a 17x19 DOE handy, seems needed often.

 

[Jbullfrog]

There are AC fittings on Ford tractors that are 1-3/16". I have used a wrench on hydraulic fittings too.

How ironic.....I just had to order a pipe plug for a M22-1.5mm thread. The hex on the fitting end is 18.5mm. I think I will use an adjustable wrench on it and save myself from getting a 18.5mm wrench or socket.

 

[Al Borland]

older core drills for concrete. Have a couple with the open end snapped from trying to get stuck bits off the drill.

 

[Wakefield]

5/8" can substitute for 16 mm

And 15/16 is close to 24 mm

Wright Tool catalogs had/have a chart of what metric and inch style sizes can be interchanged in use.
3/4" and 19 mm?
Wright may still sell some obsolete socket sizes (in 32nds of an inch?)
