Whether the contact surface of the original automobile hub nut is conical spherical or planar, and whether the thickness of the contact surface of the modified hub and brake disc has changed, such as whether a gasket or flange plate has been added, and whether the nut matches the hub well on the aesthetic level.

If you ignore the beauty, the length of the hub nut is within the safe range, and the contact surface is correct, you may not need to replace the hub nut, but there are still some riders who choose to replace the titanium alloy hub nut in order to better reduce the unsprung mass, increase the strength of the screw, ensure more safety and security in the case of fierce driving, and change the contact surface of the hub and nut.

Now let's introduce some special properties of ordinary hub nuts and titanium alloy hub 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. The hardness of titanium alloy hub nut is higher, such as grade 12.9. Generally, the type of forged nut is the most popular choice for car users, which is lighter in weight and higher in strength. In addition, the titanium alloy wheel hub nut with various color shells looks more beautiful. The titanium alloy hub nut can achieve greater hardness under the condition of smaller quality because the alloy is added with titanium metal, but the price is relatively higher.

To sum up, the selection of hub nuts is not difficult. As long as these important data indicators are understood clearly, the selection will not be wrong.

The following titanium alloy automobile wheel hub size is M12 * 1.5 * 24mm, which is produced and manufactured by Baoji Pengyuan Non-ferrous Metal. The automobile wheel hub nuts are packaged and shipped after about a week of mechanical CNC machining, material preparation, smelting, pier type, cleaning process. After the completion of production, the hardness quality of titanium alloy automobile hub bolts was specially tested, and finally the whole process was completed according to the delivery time specified by the customer.
