Bolt sizes and Thread Pitch for harness mounting points

[Tyre Tread]

Please can anyone confirm the correct bolt size and thread on the pre-tapped holes for the harness mounting points under the rear shelf.

I've tries several options none of which seem to be correct and before I bugger up the thread (access is not great) can anyone confirm for certain what the thread and bolt sixes are please?

TIA

They should work not the metric one

I think I went for the shorter ones as the thread is not that deep

Just went and tried to remove one but they are stuck fast cant see any makings on them....

I tried a seatbelt bolt which I believe is 7/16 UNF but that doesn't seem to want to go in.

An M10 X 1.5 bolt will screw in but is very loose in the thread and I was told by someone it was a 7/16 UNC which won't go in, although a 7/16 UNC nut will fit on the M10 X 1.5 bolt loosely.

Run a UNF tap down to clean the thread?

I don't have a tap in that size but if you're sure that's what they are I'll buy one.

Are you fitting a harness without a roll bar?

If so it is unadvisable as your head would act as a roll bar!

No Mike, I just want to use it as an earthing point for the battery and possibly a dog harness.
