The Sonic Extender 6mm Square Axle is a solid choice for when you can’t find your specific old or new roller hockey skate axle. The axle is built with an extra thread count to cater to many widths and will perform just like your original 6mm axle.

Square head at one end to suit Alkali, Mission, Bauer skates with a round flat head at the other which sits against the chassis. This configuration provides a higher clamping force and more friction meaning your axles won’t vibrate loose at a critical point of a game.
