found M4x6mm
Can’t you just grind off a mm?
Yes it’s a pan head, also iirc a cheese head (USA)
I've updated the post. There are a few places doing 5mm and I could probably grind it down with a lot of care. Finding the small head seems tricky.
If you’re in London try Clerkenwell Screws.
Is is a bike thing? Derailleur limit screw?
