A simple, reliable 6mm Skate / Scooter Allen Key. This is the one size that fits virtually every clamp bolt, compression bolt, and axle on a modern stunt scooter. Keep one in your bag for park sessions or in the drawer at home and you're set for setup, tightening, and roadside repairs.

Made from hardened hexagon steel for strength and corrosion resistance, with a standard L-shape giving you both reach for deep bolts and torque for stubborn ones.
