I I would like to say I set my stuff down nice and easy. Maybe once in a while. Anyway, the silver soldered washer has worked well for me, but the plastic wheels are more popular lately. For a short time, I threaded the axles after softening them up with a torch. and used nylock nuts, or soldered regular nuts. Lately, since I don't race much any more, I just dump the setscrew, and put in a regular shortened bolt for more torque, and a tapered flat if I feel ambitious..
