Introduction and a question about screws.

Hi guys :)

first of all I´d like to introduce myself.
I´m from germany and got kind of addicted to USSR lenses. Theya all perform very well on my Fuji X-T10.
I got into those lenses because I wanted good glass for cheap first, but then I realised theyr artistic character.

My question is the following:

I have some Helios lenses and since yesterday a Zenit FS-12 set with a Tair 3 (idk if S or A or...).
I had to clean a Helios lens and at the Tair to repair the diaphragma. Everything was fine and not problem at all.
The only trouble I had was with the screws. In both cases they´d broke. And I realised the Helios and the Tair used the same screws.

Does someone know which measures those screws have and where to get them?

Heres a pic in which you can see which screws I mean.

Its these screws and also the ones which are more tiny (dont have a picture right now...)

Thank you all in advance

Hi, since you're in Germany, try Oleg maybe he has some screws he can sell: http://www.okvintagecamera.com/

Only source of those screws are other lenses.
Apply oil 15 min before and use properly fitting screwdriver - then they won't break.

Yes, I agree with contronatura. Other lenses are the best source of screws.
And proper screwdriver is very, very important.
