I got this UTC A-19 transformer from ebay, read it needs "4-40" screws to mount it.
Living in Germany where 99,9999% is ISO / metric stuff, I'm not familiar with this description. I just guess it's an american / non-metric standard thread. Must be something between 3 and 4 mm from the looks of it.
Can anybody shed some light here, or even name a source in Europe where I can order such screws in small quantities? (Well, I just need 4 of them, plus a few spares ...)
Thanks in advance,
JH.
PS.: The mounting holes obviously are on the bottom (connector side). I saw there are 4 holes on the top as well. Are these threaded, too?
