I lost a Barnett on my echo 3510 today. I have a whole pile of Husqvarna Barnetts, but it seems like they don’t quite fit? Either that, or the threads got damaged when I lost the Barnett. Anybody know the answer to this?
Does echo use a different thread bar nut?

Never mind. Did some research and they don’t seem to be the same as husky. And if you are confused, they are actually called bar nuts
M8x1.25 same as most saws
^^
Yep. Only ones I've seen different are older saws made in America, poulan, Mac, homelite etc..
Even stihls are m8, there just bigger od.
My 361p has 6mmx1.0 threads with a shoulder of sorts for the bar slot. I brazed on a 13mm nut so it fits the same scrench as the others that are not tool less. 
The added length makes it easier to hold, the brazing color makes them easier to see. can't say about the 3510.
