Finding Screw Size

[jkru12]

Hi all - I bought an SBF PAM 1288 a few months ago. Very happy with it but one of the screws fell out of the crown protector and I can't find what size it is anywhere to try and replace it. The TD sent me one he thought would fit but is too big. The one on the left is the remaining screw and the size I need, the one on the right is the one that was sent as a replacement. Anybody know what size these are supposed to be? From what I've seen online it doesn't appear gen Panerai screws would fit either. Thanks!

I'd honestly go to a hardware store near you, and there is usually a nut / bolt testing station. You can figure out what the thread size is, you know the length, and request a TD provide that exact screw.

Alternatively, you probably won't see this screw head, so you could source alternatives that are the same thread size locally.

Maybe take it into an Opticians? they usually have a box of screws for the arms.

So I got calipers and discovered it's a wonky size that doesn't appear to be available anywhere - m1.6 for the thread, but a head diameter of 2mm which makes it impossible to find. The hole on the CG is 2mm so regular m1.6 screws won't fit. Oh well.

Was able to sand the head down on a screw with a Dremel to fit. With some blue loctite it's all better!
