From a sealed pack of twenty were literally TWO with the wrong thread pattern. (The shop that fits my tires says it actually happens all the time.) Not cool either; No matter how careful the shop was, the studs didn't even last the first pull. Already coming off. Useless "custom" product not worth the money at all except as a method of holding your wheels; as any delay will do. . Add to that crappy quality control; buy elsewhere.
