Replacement steel axle locking nuts with secure nylon bands. If you change your wheels often the nylon band on the rim of this nut can wear out quickly. Without this ring, the nuts don't stay in place and you can loose a wheel in the middle of skating. These are a great addition to your skate bag so you don't find yourself unprepared.
Set of 8 nuts
Most standard axles are 8mm. Most high end plates come with 7mm axles.
