Chris,

I bought a bunch of stainless steel hex cap screws to do a race rebuild on my r/c truck years ago. Very tiny stuff. I never asked, but maybe stainless set screws could also be obtained from your local r/c truck place. This kind of thing would be for 'race guys'.

....maybe....

Hmm, so it looks like I am not quite set. I am trying to replace a 1/4" long set screw that has 4BA threading.

What is 4BA threading?

I do not seem to be able to find it at either microfastners or mcmaster.

All help greatly appreciated.

Chris,

Good grief! British Association (BA)

Chris,

Good grief! British Association (BA) thread sizes? I didn't realize that this was used to any great extent these days.

For parts you might try:

http://www.modelfixings.co.uk/

or
http://www.britishfasteners.com/ (They seem to be currently out of stock here)

Alternatively, if there is enough material in the part, try reaming it out and re-threading for something in a metric size. (The 4BA seems to be equivalent to 2.8mm?) That would seem to be the better long-term solution.

You can buy BA sets

You can buy BA sets of thread makers ( for both screw and die taping ) off Ebay at fairly reasonable costs along with the modern versions so you could always make your own if you are really stuck

Well, I'm as stuck as I can be with all this great advice.

Looks like modelfixings only has the BA threads in non-stainless.

I have a belt drive reduction kinda like this that I am running out in the water. (different motor that seems to be ok getting wet). I noticed that the large pulley has non-stainless setscrews.

I actually have a die set that I "borrowed" from my father. That's how I figured out the thread size.

I think at this stage I shall be converting it to a metric thread...

Thanks again everyone.

For taps and dies, I

For taps and dies, I go to these people-

http://www.tapdie.com/

They only sell high speed steel items- don't go asking for carbon steel, you'll get the standard reply of 'we only stock high quality tools here'.

Their prices are very good for HSS taps and dies.

If you want carbon steel, which is okay with non-ferrous metals i.e. brass, aluminium then try Tracy Tools-

http://www.tracytools.com/

or Chronos
