Stand Fixing Bolts

Hi Everyone

Just got a Tacx Flux S 2nd hand but it has no bolts to fix the legs to the device.  I want to go get them from a store as im sure they are available locally but i dont know the size of the thread.  I found they are M10 but what thread size?  Does anyone have any idea? 

Dont fancy paying 30 Euros or there abouts for the assembly kit when all i need are the bolts.

Any help is appreciated!
