Neq6 centre bolt size

[kosh]

Hi all,
I'm nearing the end of my pier build, and it's time to attach the mount to the adaptor.
I dont really want to use the original centre shaft/bolt as its so long, so does anyone know the size of this bolt?
I bought a 12mm course threat which looks very close, but after a a couple of turns, it starts to cross thread the hole in the mount. Anyone who has their EQ6 on a pier got any ideas for me?
Thanks.

Hi Goran,
I can confirm my eq6 pro mount has m12 centre bolt. You may need to check the pitch of the threads. I can see 5 thread turns in my one inch nut, don't know if that helps.

It's an M12 x 1.75mm pitch thread.

Thanks for your quick replies fellas.

Ken, I think the pitch is 1.5mm on the bolt which I bought. The other option was 1.25mm which was even worse so I think you may be right. Although to the eye it's real hard to see. I'll see if I can source the other one.

Cheers guys.

Bunnings has them in high tensile packs. I went through the same exercise when I put my NEQ6 on a pier.

I made my own from an eyebolt:

Where did you get those Kunama?

Hi Glen,
Did you have any issue when screwing the bolt into the mount? After a few turns, mine got stuck, so I gave it a bit more and i think I've butchered the thread in the mount head, i'm now having trouble putting the original tripod shaft through.
The ones i bought were from Masters, same type of pack though ( high tensile 2pk ). I guess the thread is different.
EDIT: I just checked the ANSI/ISO specifications for an M12 bolt. And it should be 12mm x 1.75mm. Why o' why do masters sell 12mm in everything BUT 1.75mm pitch?

Looks perhaps like you polished them yourself too Kunama?

I bought the 2 eyebolts from Specialty Fasteners at $11.70 each and then cut and filed them down to suit.
