Default Where to get ONE 6-40 machine screw?

Needed for an old sewing machine. It's a listed thread, and I can probably
get a box of 100 from McMaster, but I only need one 3/8 long, binder or
cheese head screw. Any ideas?

Find a gunsmith. I think that's a common thread for mounting sights.

Try a hobby shop. Usually sold in pairs... maybe not any more.

Common thread in R/C. Try a hobby shop. May have to buy a few per, but
definitely not 100.

Bob,

Found some weird screws.....just checked, including #6-40 x 1/2" or
3/4" long.

If you bomb out, e-mail me and I'll mail you a few.

If you want them shortened to 3/8" that'll cost a little extra! :-)

Try a local hobby shop if possible, a lot of the rc stuff uses small
thread stuff like that.

How about Ace hardware? It is a super standard size.

I think you're confusing it with the common 6-32 or 4-40.

Ayup...6-40 and 6-48 are gun screw sizes..and are a bit hard to find.
Harder yet to find in anything over 1/4" long.

Now why doesn't this surprise me one bit?


That's easy.... you're too dull witted to be capable of surprise. What
little synaptic ability you do possess is stretched to the limit with
life support. If you diverted power to the critical thought processors
you'd asphyxiate in a matter of minutes.

Well, it just ain't right. I mean, there's 10-32 and 8-32, why
couldn't they standardize on 6-40 and 4-40? The 6-32 tap is the
weakest one in the box. If I ever break a tap, it's 6-32. Not 2-56
or 4-40 but 6-32. 6-32 is a coarse and vulgar thread for a small
screw like that. A nice little screw should have a more refined
thread.

Perhaps we peasants should revolt. Civil disobedience, uncivil
disobedience, whatever it takes. Steal the boxes of 6-32's and
throw them though the windows of the Immigrant's Rights center.

I also had this experience. Tapped some holes in aluminum and 6-32 was
flexing a lot. I tapped holes in this in this heatsink:

http://igor.chudov.com/projects/Weld...r/dscf0252.jpg
http://igor.chudov.com/projects/Weld...r/dscf0250.jpg

The 10-32 holes were much easier on the tap than 6-32. Most holes
I tapped were, fortunately, 10-32.

LOL...for a fun experience..if you have an old Colt
thumbbuster...measure some of the threads.

Colt invented a lot of new or wierd threads..as did many gun
manufactures in those days.

A friend of mine does a fair living making gun screws on his OmniTurn.
Seems there is a market out there for the ******* threaded fasteners.

The aim of untold millions is to be free to do exactly as they choose
and for someone else to pay when things go wrong.

In the past few decades, a peculiar and distinctive psychology
has emerged in England. Gone are the civility, sturdy independence,
and admirable stoicism that carried the English through the war years
.. It has been replaced by a constant whine of excuses, complaints,
and special pleading. The collapse of the British character has been
as swift and complete as the collapse of British power.

Agreed, 6-32 is an ugly looking thread.

But 10-24 is just as baaaad IMO.

I try to avoid these in stuff I design and build.

While looking for 6-40 I ran across taps I have, labelled #7-40 and
3/16"-48.

Used a 9/32"- 32 tap on a little custom design job where nothing else
would have done.

I like collecting odd-ball taps!

I can see some utility in the 1/4 40 thread. If you ever wanted to make a
micrometer adjustment on some thing it would come in handy there.

Yes. Not for appearance, but the minor diameter is low compared to the
fastener size.

I've got a 1/4-40 tap & die. No idea why. Anyone need it?

Maybe you built a micrometer in your sleep. 40 tpi = .025"/rev.


Well, I pre-inherited my machine shop from my uncle, who we have now had
to move to a nursing home. Unfortunately he has a disease which robs
him of the ability to answer my technical questions. But as I go on,
the drawer of "mystery tools and jigs" gets less and less full, as I
figure out what they're for.

Some amazingly exotic mystery items in there yet, I should post some
pictures of the more mysterious ones.

That'd be interesting. I generally ignore the what is it puzzle
threads, but enjoy the ones where someone really doesn't know.

exchange? I have some milling cutters and lathe cutters. I'm in San
