Splined wheel stud 12X1,25 L 70

A.I.Tech's spline wheel studs are made of extremely high-strength steel; the threads are obtained by stabilised rolling (a specific system to avoid fatigue cracks). They are combined with steel wheel nuts machined from billet and copper-plated to optimise screwing onto the studs even at the high temperatures resulting from prolonged use of the brakes in racing.
