EBME Forums Forums Maintenance Spare Parts US size machine screws

Dear All,
Do you know where I can get US size machine screws?
I have found sites that sell them by the thousand and specialist sites (e.g. Harley dealers) that sell them for a fortune but no standard outlets.
I thought RS did them but could not find them.

I am specifically after 10-32 x 1/2" countersunk. (Or longer)

But finding any US sizes is often a problem.

Thanks
Robert

You could try some of the model engineering suppliers. A copy of Model Engineering or any other model magazine have plenty of ads for these.

Best of luck
Dicky.

Thanks Dicky I have actually tried this and only found up to size 8.
Robert

Robert. Yes, Dicky has given good advice there. There are specialist suppliers hidden in back streets here and there (I remember a place in Edgware, and there's one in Doncaster ... to mention but two)!

But ... have you tried eBay? I find most things I need on there these days, I'm pleased to report!

What are you after, specifically ... UNF, UNC?

Have you tried Newark.com they are part of the Farnell family and items in their catalogue can be purchased via Farnell.

UNF this time Geoff.

Martyn, thanks I forget Farnell act as agents for lots of other people.

I am sure CPC abd RS used to do them but it seems no longer.
When will the US catch up with the rest of the world and go metric? It would make life so much easier.

Robert

Wye Valley ... is but one of many!

When will the rest of the world catch up with the US "Customary Units"? In fact, why stop there ... what was (is) wrong with British "Imperial Units"? May the Force be with you!

As you must know, Robert, there were good reasons (at the time) for the adoption of the UNF thread form.

PS: here's a nice conversion chart .pdf.

Geoff,
During WWII the British were seriously going to adopt the US system so that we were able to help each other out with repairs and parts etc, the reverted back to the BA system, at least they standardised on one system (well nearly) rather that having Whitworth, Cycle thread etc.
Now we are a global market it would ne nice to have a global standard. When referring to the US I was meaning all metric measurements, i.e. use litres or liters instead of their version of the gallon, and they still use bushels and peck.
I do not really mind which system it is as long as it is one.

I know a certain German manufacturer of medical equipment when it bought up its similarly named US counetrpart started to assemble their equipment in the US had to have to seperate production line running side by side but no tool or fastening was to cross the line as half was assembling the German metric equipment and half was assembling the original US designed equipment.

Yes, Robert, I know what you meant. I'm aware of the history, believe me. That's why I replied as I did.

Put it another way:- which "system" would you rather be a part of (assuming that we can't be "independent" in this modern world ... an assertion that I would challenge ... but let's leave that for another day):-

1) The United States of America (ex-Colonies of the British Empire)?
2) The USSR? Oh, sorry ... I meant the (so-called) European Union?

He can usually find absolutely anything from odd nuts & bolts in small quantities to bespoke heavy industrial type parts.
