Huh?
The one with only one end threaded is a mystery. As far as what you asked, sorry I don't understand the question.
The two stock ones shown seem to match two of the others, but since you've set them up with the bottoms at different levels it's hard to tell.

If this is CB750 there should be 4 shorter studs that go by the spark plug locations on head.

I see what you're saying.  The two to the left do not look heavy duty.  And the one with only one threaded end seems pointless.

I think you've been cheated.   :-\

And it looks like you're missing one short one.

Who was the seller.  I'd like to avoid him.

Send them to me mate, I'll buy 'em! They're not OEM Honda studs, Honda don't make heavy duty studs, what you've got there is a set of RC heavy duty studs, and the reason that two of them are "waisted" is to assist with the oil flow to the head. Those two studs sit at the back of the head either side of the cam chain tunnel.

I know that the APE studs in my K1 engine are all the same thickness (10mm) and it doesn't seem to affect anything, so I'm guessing that Russ Collins just erred on the side of caution when he made his, back in the early days when there was no-one else to ask. Cheers, Terry. ;D

What's up with this stud?  Looks like it's not threaded on one end?

you r right it is not,as I said the whole experience buying these on Ebay was a royal pain in the a$$,Now I have to machine the one end.I have a metric tap and die set,but with this I would rather bring it to a machine shop.I was wrong about these being Honda items,J&M machine I think.The only thing holding me up right now is this stupid stud!

I'm curious...
Are these studs, in general, heat treated?  You saying you threaded it brought this question to mind, because I'd imagine it would be harder to do if they're supposed to be heat treated.

If the threads are fatter than the the rest of the stud, they are rolled threads, much stronger than cut threads.

 Is the untapped portion of the std, same size as the thread?

 I would not run a cut thread stud, if the rest are rolled..asking for failure...
