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?
