Tiny screws in lenses. What sizes & where to get some?

Opticians have tiny screws to replace the ones in spectacle frames (when they fall out).

I'd try your local optical shop and your local watch repair guy. Even if they don't have them to sell they might be able to direct you to a local source you can guy such things from.

I got some screws, and tiny springs, to repair a lens off a friend of mine who builds slot racing cars, so the model world offers another choice as well.

I usually make these heads smaller in diameter on fine grain diamond disc, until they fit in thread hole. Yes, i like the fine work Smile

Another useful source in the UK for diddy screws and springs.

Have no idea whether anybody mention this already.
I just disassemble film cameras, that normally come with lens (at least this is how it happens on fleamarket). Camera mostly have all needed screws, even tiny ones for fixation of outside lens housings.
Some of the camera models, also have small metal balls that are used in lenses to make diaphragm ring to move by steps with clicking.

To me, the head shape of the glasses screws sold through Amazon do neither look like the flat head type nor the cone head type usually found in lenses.

When looking for some very small slotted cone point set screws (M1.4 x 1.5) I found this manufacturer: https://www.del-screw.com/index.html

I haven't ordered from them yet, though.

Get to know the oldest camera repair guy in your area. After you've struck up a (very useful) relationship with the old codger, in an off-hand manner, ask him how he's set for grub screws. Or old lenses that they may be harvested from. Chances are, he'll have boxes and boxes of this stuff. People who were born in the 30s and 40s had parents who survived the Great Depression, and one common theme amongst those survivors is they tended not to throw anything away. This trait would have most likely been instilled in their offspring.
