I'm looking for a replacement screw for the screw that holds the head on a Wild M3Z microscope. Does anyone know what the correct thread size is of this screw?

I have a Wild M3Z, could you show a picture which screw you have in mind ;-)

Here's a photo of where the retaining screw goes. It's a screw with a small black plastic knob for tightening with fingers.

it is metric standard 5mm thread (M5x0.8mm).

you can find a M5x20 knurled screw on eBay. 20mm should be long enough, otherwise take 25mm and shorten it.

cheaper but bigger grip

This is great info. Now I have numbers to work with.

Thanks for the help!
