I wouldn't worry about the screw too much. Your only taking light cuts as you form the ball. It takes very little to hold the insert under these conditions. Looks like I used a simple machine screw in the one I made, let it go when I sold the 14 x 40 as it wouldn't fit the replacement lathe.

Free advice is worth exactly what you payed for it.
