mine are pretty much circles from being rounded off. whats the name of them?
there the ones that has the head, then a plank bit about 5-10cm then the thread.

you'll be after 14 of 90141KT8000

Or you could get 14 similar size allen screws and some washers which will cost next to nothing

its a trip to my local sunday market for them anyway because they'd be cheap :)

For anyone which requires some bolts which fit..
you need
'A2-70 Allen Bolts'

you will also want some washers (i got mine from wilko's for 87p for 18 or something, although i got mine cheaper because of staff discount)

A2-70 is the grade of stainless, not the dimension.

I think they are M5 screws but It's been a while since I removed the airbox from mine.

oh ahah, thats what the guy told me anyway... yeah the M5 i think, the width across the bottom is 4mm
