Common use for SAE 19/32 socket?

[Teken]

What is this SAE 19/32 socket size most commonly used for?

 

[sk farmer]

not much in the last 50 years. i have never come across one. i have seen wrenches and sockets but i don't own or use any.

 

[Displaced Hokie]

aggravating me

 

[Mickey O]

15 mm nuts and bolts.

 

[crewchief888]

the only **/32" wrenches and sockets ive seen are in 50 year old sets.
ive got a few, but have never used them

 

[OccupantRJ]

If it's 12 point, it fits a 1/2" square drive jackscrew for tensioning conveyor belts, and used to fit old 40's era tie rods. Some Craftsman sets from the early 70's had one in them.

I'll be givin' that a try, I also have several around, never used them, thanks!

15 mm nuts and bolts.

so what do you use your 15 mm sockets and wrenches for then?

my late 50's SK set has a couple oddball **/32'nds sockets, ive seen quite a few older SK and CM loose sockets in those sizes.
seems like ive got a few 12pt comb wrenches in those sizes too

For keeping apart your 9/16" and 5/8" sockets

Fill the open spaces on wrench racks and socket rails, not all to common for me anyhow, didn't the older (late '70's, early '80's) GM's top alternator bolt use a 15 mm socket/wrench?

 

[Scout Driver]

Working on an old Winchester bicycle....I was pleasantly surprised that I got to use my 19/32" wrench to take loose the front wheel nuts.

[jvitez]

Wright tools, set # 424, 1/2 inch 12pt socket set has it. Page 157 of their catalogue.

use them on bicycle wheel nuts everyday

 

[SCscoutguy]

I picked up some 8 point square head sockets a while back that had a 19/32 socket in them. I have not found a square head application for it or the other odd sizes yet?

 

[Hurricane_Whisperer]

I think the British used them. I seem to remember needing an odd wrench size to adjust SU carburetors.

I have used an 11/32nd on an old GM Loco I work on. Seems like a lot of the nuts for electrical connections are 11/32nd.

 

[BigK600]

Just remember tool freaks, your set is not complete untill you have these.

 

[stock z/28]

I use the 1/32 quite a bit on automotive electrical connections, like solenoids and relays.

I "think" there was a Ford rod nut that may have used a 19/32 socket size. I have used some odd/32 sizes before but I cant remember where.

 

[Teken]

As always you guys rock! Many thanks for the edification on said socket size . . .

 

[e3pres]

IIRC, I had an S10 that used a 19/32 on the serpentine tensioner. It was a real oddball and I spent about an hour looking through old coffee cans full of sockets to find one that would fit. The truck ate serpentine belts regularly, so it had its own special place in the toolbox until I sold the truck.

 

[SCscoutguy]

Anyone have any idea on the 14/32, 17/32, 23/32 and 31/32 sockets I have?

 

[TheGrooveking]

Well your 14/32 would be a 7/16 socket, remember the ol' common denominator thing.....

When you posted up those 8 point sockets with the numbers I actually had to look twice!

Thanks for posting up those odd ball sizes!

That's strange, the service manual call for a 15mm wrench/socket.

My dad uses them on planes occasionally.

 

[philw]

I've got a bunch of old sockets like that. I think I finally found the answer in some of my old catalogs.

Seems to be that there was a handful of "standards". The old 19, 25, and 31 correspond with the old U.S. standard. The 23 and 29 correspond with the old Mfr. standard. The 15, 21, and 27 correspond with the old Mfr. standard for square bolt heads and nuts.
Maybe this will help......
19/32 = a 5/16 hex bolt by US standard
25/32= a 7/16 hex bolt ""
31/32= a 9/16 hex bolt ""

17/32= a 5/16 hex bolt by Mfr. standard
23/32= a 7/16 ""
29/32= a 9/16""

15/32= a 5/16 SQUARE bolt by Mfr. standard
21/32= a 7/16 ""
27/32= a 9/16 ""

These are out of a mid 50's New Britain catalog but other old catalogs have same info.

An early 70's Snap on catalog no longer has the sizes in the chart. They have a column for Old U.S. and old SAE but no 32nd sizes.
They have a date for the American Standard Association sizes and that shows 1965.

To sum up.....they consolidated bolt sizes in the 60's and that is when the odd sizes disappeared. Unless you are working on something old you probably won't need one....at least not for it's intended application.

rjohnson......Are the planes older than mid 60's? I suppose aircraft could have lingered on but I would think the standard would be across the board since the Snap on catalog didn't list them......but they continued to sell them for a long time.

 

[rodm1]

Dodge truck sway arms.

Before I bought the S-10, my newest vehicle was a 1976 Corvette. I'm not sure I owned any metric sockets at that time.

 

[Bruce Lancaster]

Pretty sure that flathead connecting rods were the 19/32 application that kept those sockets in the tool boxes up into the '60's. I should know that for sure...didn't bring any connecting rods to the office today, though.
11/32 was VERY common on auto electrical connections for many years. Almost irrelevant in the day...only rich toffs could afford 1/4" sets when there were pliers.

That is fantastic reference material! Many thanks for the insight there Sir!

 

[sk farmer]

so what do you use your 15 mm sockets and wrenches for then?

you guys all missed the humor. let me rephrase this. why would you use a 19/32 on a 15 mm if you have a 15 mm socket or wrench?

 

[Stick Figure]

so you don't have to go back to the box to get metric tools when you all ready have SAE stuff out.

 

[Bruce Lancaster]

Right now, I'm holding an old Snap-on 15/64! Once you get down to divisions like that, you should be able to cover about anything you encounter...Ottoman Empire mil-spec, you name it...

 

[Teken]

I wouldn't mind seeing that socket . . . Can't say I have ever seen one live!

 

[Bruce Lancaster]

Imagine what a socket set in 64ths would weigh...

 

[Scout Driver]

Last spring I got a set of "Rays" sockets that are from the 1920's. They are the sheet steel type of sockets and are all in 32nd increments.

Scott

 

[Bruce Lancaster]

"Yep, looks like I'm gonna need the 97/128th socket for that'un"

 

[gearjam1]

To my great consternation...I have discovered that this size is used on my wife's 1990 Mustang GT convertible. I have been replacing the rear lower control arms, and Ford used 19/32 bolts to secure the rear sway bar to the control arms. I work on just about everything, and this is the first time I've ever had to use this size... Maddening....

Just remember tool freaks, your set is not complete untill you have these.
