Where to get brass BSW screws?

Lots of brass screws on that link but AFAICT there aren't any that meet the spec.

say they will do other lengths if you ask them.

I'd seen those, but they're ordinary csk rather than raised countersunk.

eBay is the generic answer. Did you even try it first?

Of course! I also tried everywhere else I could think of, that's why I asked here for help. Do you have a helpful suggestion?

Some people are a bit nervous of eBay and do not realise that it is actually better than any traditional physical hardware shop (much as I like them).

If you had said you had tried eBay without success, many of us would have regarded that as a challenge and no doubt managed to locate some. As it is, I for one won't be bothering.

That's

Well definately NOT Bunces of Worthing because they seem to have called in an insolvency company :-(.

Pity because that was the goto place if you wanted all manner of screws/bolts/fastenings in small quantities, and on a Sunday.

Is brass essential?

I can get equivalent size 10-24 in UNC in A2 Stainless.

Any doubt get a tap.

Any reason why a standard countersink can't be used?

Yes, I'd seen those but I need to match the brass originals. I spec'd BSW because that's what the originals are, but I have a wide range of taps and dies so a small thread angle change would not be a problem. These screws attach the window "furniture" to 1930s Crittall window casements (which are steel). There are typically 4 screws per item by design, but several are either missing or have sheared heads, that's why I want to match; mixing flat/raised head or brass/SS would not look good. If necessary I could move screws around (so that one casement had all new, etcetera) but that would be a pain and would probably lead to more spoilt heads or shearing - using the dremel to drill-out is a royal pain and I don't want to add to the number I have to do. Also, there are rather a lot of casements. I've contacted a few suppliers now and may have found a source for longer screws with the correct head and thread, so if I can't get the right length I'll have to make a holder and get shortening. There we are: full disclosure ;-)

JOOI, would firms who restore Crittall windows not sell to you or do they not bother to match the original screws?

Crittall can't help and (so far) I haven't found anyone with the screws.

Might be worth dropping these folk a line if you've not already tried them...

Thanks, I hadn't found them.
