I would assume Eminence uses American threads... I don't know. But both American threads and metric, in a number of small sizes and lengths can be found at your nearest hobby shop. Look for shops that cater to R/C model airplane and R/C car racers. The Dubro airplane hardware has many sizes from 2-56 to 8-32 thread, and the R/C car hardware (orange and yellow packaging) has a lot of metric sizes.
