Harness bush conundrum

[BertBert]

I am confused about the bushes in my clubsport in the chassis for the harnesses. They seem to be imperial rather than metric. Certainly they are very close to M8, but a finer thread. So I am assuming they are UNF. However, the bolts are extremely hard to wind out as if they are the wrong thread. Basically I am a bit confused!

Anyone know what is going on?

Thanks

I found the same thing, they are imperial not M8 I used some copper grease when I refitted them and they were fine!

That's a shame as one of them has had an M8 wound in to it!

Need some imperial taps I think to clean them out (not the one with the M8 in it).
