Sanwa joystick ball unscrewing

Anyone else having an issues with the sanwa balltop joysticks? It seems to unscrew in middle of games for me. Do you do anything special to get it extra tight? I’m usually just holding the stick part and screwing the ball till I lose grip.

put a flathead screwdriver in the other end of the stick (there’s a slot), then try tightening it again. You should be able to get another half-turn or so.

haha i feel noob did not notice that there was a flat head on the other side.

Thanks by the way.
