General Fiat Qubo Roof Rail bolts

[Marcus111]

I have a 2012 Fiat qubo. I bought it second hand and it came without the long roof rails that other qubos have. I found a pair if roof rails second hand. after struggle I removed the plastic covers to reveal the bolt holes. However this did not come with any screws or bolts and I cannot fins any sizes or information online.
Does anyone know what size screws or fasteners come with the roof rails?
Many thanks

M 10 most likely

17mm spanner.. are they really that big ?

M6 is what I meant! Woops.

Thought so..10mm hex

The Panda ones are M6 (10mm hex), so a good place to start.

Be careful with the length. The hole will be blind, to prevent a leak point, so don't bottom out the bolt and either break through, or leave the rail loose. The Panda ones are quite short. Easy to cut the ends off a longer screw.
