Thanks for that info.

M3.5 seems to be as rare in Australia as 6-32. I used to have boxes of 4BA stuff, but they have long disappeared in about 10 house moves Ove the last 30 od dyears.

I have ordered some 6-32 screws, counter sunk and pan head,? I had to order 25 of 1 and 15 of the other to make up ?the minimum $10 order, then pay 11 dollars freight, probably would have been cheaper from the US.

Next I just need to get a socket for the GPIB interface, which also seems hard to get , at least in reasonable quantities

Hi all

The threads you are looking for are M3.5, this is a little used thread except in the UK where it is used by electricians to hold switch face plates in place, it is actually very close to 4BA which were the original screws used..

HP used this thread in place of 6-32 when NATO and the US military required all threads to be ISO Metric. The tapping hole diameter is almost the same for 6-32 and M3.5, it is predominately used in case work only, particularly castings.

Hope this helps

If it's indeed M3.5 x 0.6, it's the same size as the hardware used on the recent HP-IB connectors, the ones with black screws (early HP-IB connectors used uncolored stainless steel 6-32 American hardware). You can check for compatibility with the screws on an HP-IB connector.

This is indeed a metric size, but a very unusual one which is not easily found, even here in Europe. Very few hardware vendors have them, one of them is here :

(no affiliation with them).

I hope this helps !
