The Eibach M14 x1.5 wheel nut is a tapered-seat lug nut with a 19mm hex head and a 25mm body length, made for applications calling for M14 x1.5 threads and that nut size. It secures wheels by matching thread pitch and taper geometry while providing the correct head size for standard sockets and reliable clamping where that specification is required.
