10 Axle Keys - Scroll Down

Axle keys are parallel or pegged inserts that sit in matching keyways so the kart axle and a hub, sprocket, or brake disc rotate together and transmit torque without slip. Common karting sizes include 1/4 in square keystock and 3/16 in by 1/4 in thin keystock, plus three-peg keys made for 40 mm axles.
