The PowerDyne Y3 Skate Tool features three tools in one! This multipurpose skate tool is designed with a 1/2” socket for axle nuts, a 9/16” socket for kingpin locknuts, and finally a 15/16” open wrench for toe stop locknuts. The Y3 is a great tool for most plates, and one of, if not the best tools for roller skate plates that uses a washer and nut system for toe stops (most nylon plates and PowerDyne Thrust plates).
