Looking for 6-32 Threaded Screws in the UK

small screw used in equipment. One screw size one will seldom see
here is 5 (not sure if it's 5-36 or what), which is now getting even
rarer, because barrier terminal strips that used to have them are now
using metric screws instead. Maybe because they're being imported
from overseas?

It's 5-40, and it hasn't disappeared yet. 3-48 I still occasionally see too.

Sizes 7, 9, and 11 really have disappeared.

I'd say so! I've never seen an example of any of those sizes, and
I've seen a lotta screws. I remember that one screw size was
specified as a fractional inch, like 1/4x20, but it was also specified
as a 13, I think it was.

When you come to think about it, it's odd that the U.S. screws were
given numbers that were not directly related to a physical size. Like
an M3 metric screw is actually a 3 mm diameter. Well, the U.S. screws
could've been spec'd in thousandths of inches, like a #6 screw would
be something like 140-32 which would be 140 thousandths inch diameter.
In any case, you get the idea. Something much less counterintuitive
that would make it unnecessary for you to look up a screw size in some
obscure chart.

Occasionally I still see #14 stove bolts, which are pretty close to 1/4-20.

The "US" number system actually makes a lot of sense as a kind of logarithmic
scale. Sort-of like resistor values but instead of expressing the actual
value you state the position in the series...

At least it ain't as bad as wire gauges, which are backwards - larger
wire has a smaller number.

Maybe someday the forces of conformity will take over and the U.S.
will go to metric (Yeah, I know, I'm dreaming).

Like someone else said about the russian equipment that had some
obscure numbers which were in reality a garden hose fitting, maybe
someday the U.S. screws will all be given some metric numbers, and
everything will be thrown in together. Then over time all us old
farts will die off and the newer old farts will say, what's this doing
here? Let's just forget it. And they'll float forever into
obscurity. Nothing like obscurity to take care of things.

It's happening.

A friend in the auto industry told me that all their new design work
is metric. That was many years ago. That alone will make sure
that tools and screws/nuts etc are easy to get. Local hardware
stores now carry metric screws...

Many of the drawings for packages come with both inch and metric
dimensions, and often with a note like "controlling dimensions
are metric". CAD tools often support mixed units...

Hello,

First of all, apologies for the off-topic question but I thought some of you
may be able to help. I'm looking for "6-32" threaded screws, whatever that

I once spent the better part of a day in Bogota seeking Metric machine
screws, so you have my sympathy. At least you speak the clerk's
language!

However 6-32 bolts are readily available (for a bit
more money), from all the aviation suppliers. Basically probably 75% of the
World's aircraft, use the UNC threads, and hence these sizes are readily
available.

Well, sort of... one of the 'bad uncle' issues with the International
Space Station, is that it's half metric and half SAE [Society of
Automotive Engineers -- the standards body for UNC/UNF etc.]

Don't Ask how that came about; I don't know and don't want to..!

What I find is that the American NF sizes which are the finest
pitch, are still much coarser than the metric pitches.

There is also NS -- National Special. It's finer than NF.
One use I recall: the thread on Icom Rubber Ducky antennas was NS.

Hehe... Well, finally I managed to find them in the UK... Not a great
selection, but better than nothing. Also, the screws used in PC hard drives
are also 6-32, so a visit to a computer shop should be enough for small
quantities...

They have machine screws are zinc plated (galvanized ?) and they have

6-32 screws *are* UNC. Small UNC/UNF sizes go by numbers. 6-32UNC is size
6, with 32 threads per inch, UNC thread shape.

You should be able to get 6-32UNC from Newark, via Farnell (same company).
They'll probably charge for shipping from the US.

I bet RS have them, too.

BA (British Association) screws are something else altogether.

Do you think he still needs them after 10 years? He posted that

Hey, we had a 20-year-old one resurrected in sci.optics a few months ago.

To the (2013) OP: Screwups like that are worse on Usenet, because
there's a large appreciative, and largely underemployed audience.
(Michael isn't one of them--he gets a pass because he spends so much of
his time helping people, gratis, under very difficult conditions.)

However, your helpful attitude to the (2003) OP is also duly noted.
Welcome to the sci.electronics newsgroups. Do hang around and help us
dilute the other sort.

Cheers

Phil Hobbs

My screws where purchased 01.06.01 05:52T00:00 . I still use them.

Sometimes I just miss USEnet.

I bought some in the '60s, but I keep buying more. I've bought 20
pounds at a time, and still ran out.
