Duncan/Yoyo Jam axle size


I was wondering what size Yoyo Jam axle (small, medium, standard, large) has the same outside diamter as duncan yo-yos. Simple I am seeing what size Yoyojam axle can fit duncan bearings?


I don’t know what size the Duncan Axle is, but th YYJ Standard Axle is: 3/4" length 6-32 cup point set screws.

I found the info here: http://www.yoyonation.com/talk/index.php/topic,36558.0.html

You can find them at Lowes Or Home-Depot. Or, just any online stores. I went to Home-Depot, and I got some of these for my DM.
