I am thinking of adding a spacer to raise the dovetail of my Zeiss 60w illuminator in order to get it to fit on a beam splitter cube which has a Telan lens on it.

Need a screw that is about 10mm+ longer than this one.
Can anyone identify it?
Diameter of thread is 2mm, diameter of head is 2.8mm (has to fit in a 3mm hole. Thanks

Last image shows simulated setup.
The idea is to have both the 12v 60w and an electronic flash connected.

I might have some of the screws used to attach bayonets to a Photomicroscope head (not the illuminator attachment), but it won't be easy to find them. My experience with Zeiss screws is not encouraging. They seem to have used a multitude of non-standard screws, so many that it looks like they designed new screws every time they designed a new piece of equipment. Even when the thread is standard, there is often something unusual with the screw length, the diameter and shape of the head, or other peculiarities.

Thank you enrico,

I have noticed some variations in the screw length between some dovetails.
I am hoping that in this case the thread is standard - I suppose it might be possible to adjust the length if necessary.

Adding a better photo of the screw:

Have been told that it is likely a M2 0.40

Thanks all
