Is the contact surface of the original titanium wheel lug nut conical, spherical or planar, whether the thickness of the contact surface between the refitted wheel hub and the brake disc has changed, such as whether gaskets or flanges have been added, Also, on the aesthetic level, whether the nut matches well with the wheel hub.

If the aesthetics are ignored, the length of the hub nut is within the safe range, and the contact surface is also correct, then there is no need to replace the hub nut, but there are indeed some riders who choose to replace the titanium wheel lug nuts in order to better reduce the unsprung mass, increase the screw strength, ensure more safety and security in the case of fierce driving and the change of the contact surface between the hub and the nut.
Now let's introduce some special properties of ordinary hub nuts and titanium wheel lug nuts
1. The ordinary cast wheel hub nut is actually the nut used by the original factory. The hardness grade is above 8.8, which meets the requirements of daily driving.
2. Titanium alloy hub nuts have higher hardness, such as grade 12.9. generally, this type of forged nut is the most popular choice for car users, which is lighter and stronger. Moreover, titanium alloy hub nuts look more beautiful with various colors of shells. Titanium nuts, due to the addition of titanium metal to the alloy, can achieve greater hardness in the case of smaller quality, but the price is relatively higher.
To sum up, it is not difficult to select the hub nut. As long as these important data indicators are understood clearly, the selection will not be wrong.
