Brompton Chainring bolts

[Kell]

Anyone know the spec for the Brompton Chainring bolt that goes into the crank arm on the reverse?

This one:

That's the bolt that's somehow sheared off. While I can buy another full set, it would be better if I can just get one (or several of that one) as I don't use the others with this current set up.

According to some data I've found online, it appears to be an M8 x075 and it's 14 mm long.

I've just going to order a new set as I'm not sure what else would fit.

Have you checked SJS?

I ordered from Brilliant Bikes as SJS charge delivery. And I asked them about the possibility of buying a single bolt.

...and they said no.

Used blue loctite on the threads when I changed my chainring to a 44. Been fine since 🤞

Took it all apart this morning.

I “think’ the threads inside the crank arm have stripped rather than the bolt snapped.

Either way I need a new drive-side crank arm.
