Yup. Standard metric threads correspond to "Coarse" threading. So M8 is 8mm x 1.25. "Fine" 8mm comes in two flavors: M8x1, and M8x0.75.

Whoa this thread kept going!
If anyone cares for an update:
My local hardware store didnt have fine threaded M8 so I ditched that.
Then I got a parktool HCW-5 to remove the lock ring and I tried the correct direction for my BBT32 and still no luck.
The lock ring wouldn't come off either (I thought I could remove the drive side without removing the lock ring but no).

So I decided its a super cycle and probably worth less than my tools so I gave the bike to my local neighbourhood bike coop

Oh well....the important thing is that I tried...I think thats the moral of this story

So you tried ONE source for a bolt (not the one I recommended either) and you gave up.
That's a "moral"?

I was joking about it being the moral of the story. don't all stories have morals?

The biggest thing was that the lock ring the the cups really didnt seem to want to come off. I did a decent job of keeping force applied to the BBT32 in the beginning too. I think the bolt would be better but I thought the bike wasn't worth enough to keep messing with my tools.
My bbt32 teeth were starting to get chewed up and its brand new.

If there is one moral to this story it what I always teach my students: The threads on the bicycle are designed to un-thread if the bearings fail, hence the left hand threads on the right side of the bike. Stoopid simple but rarely recognized for the simple application for practicality and for bicycle mechanics to understand. Just my two cents worth, MH
