These nuts look great. My only complaint is that when used with an impact wrench or when tightened to specification, the safety tool binds a little like it's too big.
Pros
β INSTALLATION: This product will only fit wheels with M12X1.5 bolts and a 60 degree tapered fit. Before assembly, ensure that the seat, thread size and height of the studs match these nuts. Please hand tighten the jam nuts, DO NOT use power tools.
