No, Pro-Line's do not mount like 1/8 scale hexes with a grub-screw through the axle end holding the cross-pin tightly in place...they have a groove in the back that fits over the cross-pin in the axle, then a 5mm lock-nut goes onto the axle-stub, tightening the hex against the criss pin...completely different than the 1/8 or CEN style.
