Fuel filler cap bolts

[Bmac]

I've had to hack off the bolts that hold on the fuel filler cap. For clarity, this is the flap that you open and close, not the actual cap, the ones that are captive within the plastic.

Can anyone advise on what I should be replacing them with?

This is one that survived:

Thanks.

These come with the fuel flap, so I’d just measure the bolt length and the thread, then get a few hex bolts and nuts to match - preferably Black.
