Go Pro bolts

[morite]

Hi All,

I am looking for a bolt for my go pro housing as I have lost one.

Does anybody know what size I need (M8x25mm or whatever it is). I couldn't find what I need or the size when searching amazon, google, etc

I want something like this but without the thumbscrew part, just an allen key head https://www.amazon.co.uk/TNP-Gopro-Thumb-Screw-Black/dp/B01KHFWGEK/ref=sr_1_1?keywords=gopro+bolt&qid=1564930248&s=sports&sr=1-1

Thanks in advance
