Technical Screws to catalyst

[menola]

Hi,
Simple question, are the screws mounted in catalyst next to the first exhaust-pipe or are they loose bolts? I am just planing my job to replace the first exhaust-pipe after the catalyst. Witch size has the bolts? M10, M8?

Assuming it's for the 1.6 engine you've posted about before, ePER shows it as studs mounted in the flange of the cat.
