Ceasar:
Yeah ha ha, a new thread thread, which shows that reusing English words
isnt always a good idea (thread now also stands for a linked group
of bulletin board posts as these are).

Does that thread pitch gauge work for very small threads too? This is
something i might look into getting because this turned out to be
a pain, and same problem with my monitor in the other thread.\
I think the conclusion now has changed a little because i found out that
i was estimating the thread pitch incorrectly somehow. I found a better
way now although it is not easy to do. What i do now is line up a bolt
with a ruler (it has to be a good ruler too or this wont work right)
and look at the first thread with a magnifier (eye loop). I then carefully
hold the bolt steady against the ruler and move the eye loop down the
threads counting the threads until i reach 1 inch exactly (the 1 inch mark).
If the last thread aligns perfectly with the 1 inch mark and i counted
32 threads then i would assume 32 threads per inch, but if the last thread
peak is even 1/4 of a thread width (peak of one to peak of the next one)
short i call it 0.8 pitch instead. This allowed me to tell the difference
between the 32TPI standard thread pitch and the 0.8mm metric thread pitch.
I then went back and used the same technique to measure the other threads
too and found that the smaller size was M4-0.7 and im sure of that now.
I also ran to Home Depot again and picked up some M4-0.7 screws and they
are the same too. Since i checked these over i was able to determine that
they are both metric sizes, it's just very very hard to tell the difference
between the 32TPI and 0.8mm pitches because they only differ by 0.25 of
a thread distance over a 1 inch span, and the 10-32 nuts fit the M5-0.8
bolts too, just a little tight at first, then loosen up as they are turned
and backed off a few times.
I'll have to keep in mine the limited strength and use them for apps that
are not that important too i guess, thanks for the suggestion.

Yeah that's what i found too, that the very old homes were built with REAL
two by four's ha ha. I had that same problem a few times with adding sheetrock
when the original material was lath and plaster...the newer construction
had to be shimmed out to meet the bigger older lumber sizes so the walls
would look smooth. Also, i found many constructions to be built with the
studs on 2 foot centers instead of 16 inches like they are now, and some
had to be shimmed to the side too because they didnt reach to 2 feet exactly
but where off a little so the new material didnt match up right. Geeze.
Dean:
Oh ok thanks. That means that M4 implies M4-0.7, which is good to know.
I guess they assumed that in the manual for my monitor too, but more about
that thread in that other thread
After all this pain in the neck stuff i am thinking of looking for one
of those thread gauges or something anyway. I never had this problem
before because i used all standard thread stuff.
