Default 3mm Dubro Ball Link coupler

I got some 3mm Dubro Ball Links to attach to aluminum servo arms that were tapped for 3mm threads. All good there.

My question is what type of coupler to use? I normally attach a Sullivan eye bolt to these ball links but they only come in 2-56 or 4-40 thread sizes, not 3mm.

Does anyone know where I can get 3mm threaded eye bolts or can a 4-40 eyebolt go into the shank of a 3mm Dubro ball link?

thanks

I got some interesting information back from Dubro. Their 3mm Ball links are actually compatible with both 4-40 and 3mm threaded couplers / eye bolts. Either one will work they said. Sharing since I think others will find this information useful.
