Hi Don,

Thanks for the tip on the stock spring anchors.

The only problem is, I can't find a nut that is only 5/16" flat to
flat, that will work with the 1/4-28 thread. They seem a little high at
3.00 each, it seems a machinist could make a bunch for alot less.

I just made a new post in the forum which explains the problem more
fully, and has a link to a small GIF drawing of the anchor.

Thanks again,
John


You might look for electronic hardware. www.Newark.com has 70B9168 which is
a 1/4-40 nut used for small toggle switches ($0.27/ea). Some small pots
have that size or perhaps 1/4-32 or 1/4-36. Also, many panel meters have
1/4" studs that are very fine pitch and small pattern nuts, and the studs
are about 1" long (some might be longer, especially switchboard meters),
but usually brass. You might find a lot of old surplus meters you can
cannibalize, or you might get replacement studs from a company that
specializes in analog meter modification, such as www.weschler.com. I have
some old meters and studs from when I used to work at EIL, which was
eventually bought by Weschler.

Also, you might look at rod couplers, which are smaller pattern than nuts,
and also threaded spacers.

Good luck,

Paul

Hi Everyone,

Can anyone please tell me where I can find some 1/4-32 or 1/4-40 screws
about 1.8" long. I can cut down a longer screw. I don't need a head on
the screw, so I could cut the head off, or use threaded rod stock.
Cutting the head off the screw may be cheaper.

I'm going to drill a hole through the screw at one end and use it as an
adjustable spring anchor. Due to space limitations, I need to use a
small pattern hex nut (maximum 5/16" flat to flat) such as the Part #
91862A516 from www.mcmaster.com. They also make a 1/4-40 nut at
slightly more cost.

I could not find a 5/16" hex nut to work on a regular 1/4-20 or 1/4-28
screw, so that's why I need to find a 1/4-32 or 1/4-40 screw. If I
could find a 5/16" hex nut to work with a 1/4-20 or 1/4-28 screw, that
would also solve my problems since 1/4-20 or 1/4-28 screws are more
easy to find.

I would appreciate any help anyone can provide with finding a source
for the screws, or any feedback.


Hi John:

Have you already tried looking at McMaster's pre-made spring anchors? Take
a look at their part no. 9634K14.
