M4 instead of m3.5

I just came back from 4 hardware stores.

I’ve got everything except M3.5 screws

Even got M3.5 nuts but M3.5 x 20 is impossible to find.

It seems that it’s quite hard to find those here in SE Europe.

Can I use M4 screws?
Is there enough room to fit them?

Thank you!
Regards,
Walter

M4 works great for me. M3.5 are impossible in Argentina also.

Yes, no problem with M4
If it doesn’t fit perfectly, just drill the holes a bit wider

Thank you guys!

You’ve just saved me from a lot of grief trying to get those screws!
