Tuner carriage bolts conical from McGard are designed for wheels with narrow diameter holes. Here the outer diameter of the bolts and the wrench has been reduced a bit. McGard's Tuner products meet all the requirements of the automotive industry. European automakers usually use bolts to secure the wheels.

Manufacture in a cold extrusion process ensures that the carriage bolts correspond to strength class 10.9.
Tuner carriage bolts are manufactured in two parts so that the carriage bolt head can be hardened to 46-54 HRC. The carriage bolts are coated with Geomet. This coating ensures that the color is guaranteed when the carriage bolts are loosened and tightened several times.

Furthermore, this coating offers excellent protection against corrosion and difference.
