Yes, 25/32 is almost exactly 20 MM, but 15/32 is under a half inch so not 15 MM. It's actually just a hair under 12 MM. I still use a fair bit of metric so when you wrote 15 MM I knew that didn't sound right.
Don't pitch those oddball sockets you may need to press out some u-joints or need to weld up some Rube Goldberg tool.
I have a double ended open end wrench that is 7/8" and 25/32". I found it behind the seat of my '41 Ford Truck. Working on the dash of my '50 Ford an 11/32" nut driver or socket was indispensable.
Begs the question why don't they standardize a ton of stuff on a given "class" of car/engine like sparkplugs, tie rod ends, fuel and oil filters, air cleaners, bolt sizes on common parts like exhaust manifolds, bell housings, etc., etc., etc.
Only good ues of a 25/32 socket is to use it in a press as a spacer.... maybe for a small u-joint? Sent from my iPhone using The H.A.M.B. mobile app
I am really into "traditional" ignition systems and have run into a lot of 11/32" nuts. I would even say that they are common.
Sorry, I ment to say that those Utility Boxes were mostly all Aluminum and very well constructed, the fasteners are steel.
The 11/32 is standard for 8-32 nuts, I use them all the time - I think the 25/32 is to keep social distancing between 7/8 and 13/16... Actually I'm pretty sure I used my 1/2 drive one as a spacer for a bracket on my golfcart...
I know what I have to do now. Tomorrow is my only day off this week, and I’ll spend a few hours hunting down all the oddball /32 wrenches and sockets I have and post a pic of them. Another way I have to waste perfectly good time on something meaningless Thanks all!
OOOPS!!! Working on my F100, just stopped to read for a moment: I meant 19/32". (15mm) Sorry, guys. (no google, just my realization over 60 years of 'Hey, this socket fits VW head nuts...' LOL
Psst, hey Mike. Take the decimal inch number and multiply by 25.4, than will give you mms. Take the MMS and divide by 25.4 and that will give you the decimal in inches. Google is easier tho, lol was
I always thought those odd sockets were to pound on a nearly rounded bolt or nut. You know the ones, the ones you rounded with a worn out 12 point socket or an adjustable Crescent wrench!
how about tap sizes. years ago i rebuilt my fathers farmall h engine. the radiator studs were not 7/16 or 1/2 thread, they were in between. this is early 40's. cornbinder made their own stuff so you had to buy from them. damn line tickets......
The S terminal on a Chevrolet starter used to take an 11/32” socket to get the nut loose or to tighten it up. Sent from my iPhone using The H.A.M.B. mobile app
I have some oddball sockets as well as some wrenches that are in /32s. I don't remember how or where I got them, and have only rarely ever used them. When I have used the sockets, it was to grab a corroded nut or bolt, when the right size was too loose. Bob
