Well it says the S in UNS stands for Special, but I can't find 5/32-32 on there...I'm not saying it isn't there but so far no luck finding it.

Thanks pinkie.

What rivet nut kit did you buy, Marty?


About 6 months ago I went outside to lock up two vehicles with my spare fobs.  After that I couldn't find them anymore.  Looked in the garage, looked everywhere in the house, looked in all my pants pockets....no luck.  I knew I had brought them back in because as a lazy sob I never took them out of my pocket.  Fast forward to last night.  Wife dropped her fob on the tile floor and it separated into all of it's pieces.  Took me an hour and a half to put it back together as she would have no way to get to work except via my truck.  I went into overdrive again looking for the spares and was sitting on the couch and thought...I wonder if they fell down into the right side?  Put my hand down there and found not only the two fobs but two USB sticks I've been missing and thought that I had lost.

Convert the fractional dimension to a US standard screw diameter and you get a number 8. So what you really have is an 8-32, common as the day is long. Readily available from virtually anywhere that sells screws (Easy Boys!) such as Homely Despot and Lows, etc, et. al.. Same thing as a 3/16" diameter screw major diameter- convert it to the much more common standard #10 and you have one of the most common small screw sizes used in the US.

OK then, now on to something completely different.

 This question sort of fits here in "A thread about nothing at all..." because 1) it's about a thread, as in a thread of a machine screw; and 2) I'm finding almost nothing at all when I try to research it.

What is a 5/32-32 thread size used for?  ???

Is it British?   Specialty automotive?  A special size for Helicoil usage?  Perhaps an old obsolete size? I've search through many online charts of screw sizes, zooming in on many photos of thread checker kits and fixtures. I even searched through my old high school copy of Machinery's Handbook which I thought for sure would have the answer.  No. So far the only thing I've found is that there are both taps, dies, and screws of that size available, but for what I don't know.  I have found both NS and UNS designators on some of the taps and dies available, but I don't know if the s stands for special or superfine or neither.

I ask this here because some of you are a lot more experienced than I, and also have knowledge of and access to references that I don't even know exist. If I can't find it in Machinery's Handbook then I assume it doesn't exist, at least until now.

edit: Why do I ask?..short story is I purchased a set of steel nut rivets or threaded inserts if you prefer, and I noticed that it included 80 5/32-32 inserts that I had never seen before and didn't fit any of my thread checkers, neither metric or SAE so it got me to wondering why it was included and what was it used for?

No, the set I purchased had those (#8) as well, and using a thread checker, the 5/32-32 would go loosely onto a 6-32 and only just start on a 8-32 but not go all the way on it.
I also found it strange that the rivet size for the 5/32"-32 was larger than for the 8-32 even thought the major diameter would be smaller. ???

I'm beginning to think that the 5/32-32 is a Whitworth cap screw size possibly out dated, as I'm told it's listed in a 1957 version of Machinery's Handbook, but I couldn't find it in my '66 edition. Maybe if I reach down into the cushions of my sofa I'll find an earlier edition?

I believe there is a mistake in that selection in that I cannot find any reference to a "UNC" (Unified National Coarse standardized thread) measuring any fraction less than 1/4" or 0.250" diameter. I believe it is some foreign (meaning some company that is not following the standards) invention that does not really exist.

From Wikipedia:

"Designation
The standard designation for a UTS thread is a number indicating the nominal (major) diameter of the thread, followed by the pitch measured in threads per inch. For diameters smaller than ​1⁄4 inch, the diameter is indicated by an integer number defined in the standard; for all other diameters, the inch figure is given.

This number pair is optionally followed by the letters UNC, UNF or UNEF (Unified National) if the diameter-pitch combination is from the coarse, fine, or extra fine series, and may also be followed by a tolerance class.

Example: #6-32 UNC 2B (major diameter: 0.1380 inch, pitch: 32 tpi)"
<end quote>

This has also been my experience over years of actually working in the fastener industry.

Put more simply, I thinks whats ya' gots dere is 'some guy's' imaginary version of a "standard" thread that is neither standard or even in use anywhere.  ;D :o :o  Brown and Sharpe (machine tool and measuring instrument Co. located in RI and an industry leader) used to make up their own threads, such as 17 1/2 TPI, but they were not standardized threads, rather a deviation from <any> standard to force a machine owner to purchase ONLY B&S hardware going forward. As you spec. sheet calls out "UNC", this would indicate a true, unified, standardized thread but I can not find any reference to any such thread. Such my thought that it is either some type of linguistic translation mistake, or a thread made up on the fly from someone's fertile imagination. At any rate, I betcha' you have several life- time supplies of rivets for screws you will never actually see and / or find. :-)

I really have to laugh a bit, and remind folks that screw threads are very specific to certain "markets"... and having speant 45 years in designing "stuff", and having to be able to adapt, and supply the standards, I'll share this "tidbit"..

sewing machine screws.

altogether different and various obsurd sizes existed, as did the elusive 5/32-32 (its not a "UNS", or "UNCS") and does not "convert" to a modern series at all.
(I worked for a few years for a company designing multi head computer controlled embroidery machine... it was a nightmare of data to "re-absorb" in that industry, to adapt ancient to modern tech)

here, scroll down to the bottom.. you will see the tap data, and specific number.
https://www.singersewinginfo.co.uk/screw_threads/

iirc it's also a 55* thread form, not a 60*.

5/32"-32 is a British Standard Whitworth size/thread. 5/32" diameter and 32 Threads per Inch.
https://en.wikipedia.org/wiki/British_Standard_Whitworth
The size is listed in the table (4th row from the top).

The most common usage was and still is for Meccano screws.

That may well be so but if you go to the link, the page displays the specific contents of that package and it says:

"【Package Details:】:
Thread -------------- Drill Hole Size --------- Quantity
8-32UNC ---------------- 0.23'' ---------------- 80pcs
10-24UNC -------------- 0.27'' ---------------- 70pcs
5/32"-32UNC ---------- 0.27'' ----------------- 60pcs
1/4"-20UNC ------------ 0.35'' ---------------- 40pcs
5/16"-18UNC ---------- 0.43'' ---------------- 30pcs
3/8"-16UNC ------------ 0.52'' ---------------- 20pcs
1/2"-13UNC ------------ 0.67'' ---------------- 20pcs
Total Quantity: 320pcs  "

They clearly list 5/32 as UNC, which is an American designation for a Unified National thread. And there just ain't no suchofa' thing.

Of course this could well be a misprint but I can only base my thoughts on the information available. And Marty went through the Machinery Handbook (an excellent, perhaps the best available, for machine and precision specifications) and could not find anything about a 5/32 thread in the Whitworth or any other section, per our conversation yesterday.

Whatever it is, I do not have anything I could fit into that thing.....   ;) ;D
