This Eibach wheel nut is a taper-head lug nut with M12 x 1.5 thread and a 17mm hex engagement, designed to seat correctly in tapered wheel lug holes. Offered as a direct hardware replacement, the nut provides standard M12x1.5 thread compatibility with many passenger vehicle wheel studs and uses a tapered seat to ensure secure wheel mounting where taper-head lug nuts are required.
