3BA CSK Slotted Head Screws

Hi Peter, You managed to get me looking in places I haven't been for quite a while. Unfortunately Telephone engineers used only even BA nuts and bolts & the few 3BA I found have the wrong head. The odd number screws are generally only used on a few electrical items.

i really don't know what size they are though ..think they are 3.5mm by 1 inch long

its very hard to measure the pitch as its so small.

If you need enough to get past the minimum order, EKP does both brass and steel

Many thanks for all the offers and links, Colin Docherty has very kindly offered to send some to us.

They are for a BT-H magneto, the version with screened plug leads. The screws hold an adaptor plate for the different brush holder to the standard non-screened version.
