Ring 01636 636735, sorry I don?t know the bloke?s name but
I was there this afternoon buying 5/16 bsf bolts. Whilst I was there he sho
wed me his vast stock some of which was brass bolts af various sizes. Can
?t guarantee he?s got what you want but there?s a c
hance.
He lives near Newark and stands the Newark auto jumble regularly.
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.
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.

Same major diameter, same pitch although 60degs thread rather than BSW
55degs.
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 ;-)
