What Type of 2023 Audi Q3 Wheel Bolts Are Best-xu (2)

2023 Audi Q3 wheel bolts act as fasteners to withstand the shear forces caused by vehicle acceleration and deceleration, engine power drives the drive shaft to turn the wheels, and the tires create friction with the ground to drive the vehicle forward. Stock wheel bolts are typically set to Grade 10.9, which is suitable for most sedan loads. Suppose you want to install personalized aftermarket wheel bolts. In that case, BONOSS recommends the high-performance Titanium 2023 Audi Q3 wheel bolts and Grade-12.9 wheel bolts, which are superior and more durable than other wheel bolts.

Is Rust-proof Important for 2023 Audi Q3 Wheel Bolts?

Rust is the biggest problem for wheel bolts, and good wheel bolts should be adapted to various complex environments. Aftermarket 2023 Audi Q3 wheel bolts generally use 10.9-grade chrome plated steel, the surface chrome plating can play a good role in rust prevention, but with time, the rust prevention layer may fall off or be damaged. Chrome plating is not an environmentally friendly and efficient rust prevention technology because chrome plating can easily lead to hydrogen embrittlement.

Hydrogen embrittlement is the hydrogen dissolved in the steel, polymerization of hydrogen molecules, resulting in stress concentration, more than the strength limit of the steel, and the formation of small cracks inside the steel. Hydrogen embrittlement can only prevent, not cure. Once hydrogen embrittlement is generated, it cannot be eliminated. Internal residual or applied stress causes 2023 Audi Q3 wheel bolts embrittlement or even cracking.

Advanced rust prevention technology has been applied to the high-performance 2023 Audi Q3 wheel bolts, such as electrophoresis, hard anodizing, etc. BONOSS has applied more efficient rust prevention methods for different materials. Grade-12.9 wheel bolts have electrophoresis rust prevention on the rod section and have achieved 192H rust prevention time in the salt spray test.

Forged aluminum alloy gaskets use hard anodized rust prevention, and the aluminum oxide layer prevents liquids and air from corroding the inside of the metal. Titanium 2023 Audi Q3 wheel bolts use a hard anodized thickened titanium oxide layer, using the same principle to prevent wheel bolts from rusting. Still, the titanium alloy itself has extraordinary anti-rust properties.

What Are 2023 Audi Q3 Wheel Bolts Best?

The washer type 2023 Audi Q3 wheel bolts cushion external forces from ground feedback during vehicle travel, which helps the wheel bolts maintain a fixed torque. Depending on your wheel seat, it can be set as a spherical or tapered surface. The integrated wheel bolts will directly affect the torque when subjected to external forces, which can lead to loosening and dislodging if the force is too high. The same structure is used for lug nuts, but the disadvantage is the rust resistance of the material. Rust will cause the metal to increase in size, which is why the above-mentioned rust resistance is very important for the 2023 Audi Q3 wheel bolts.

The use of SCM440 steel alloy or titanium alloy material will ensure that 2023 Audi Q3 wheel bolts have sufficient strength to withstand vehicle loads. SCM440 is considered the standard material for 12.9-grade wheel bolts, and ultimate tensile strength and proof load are considered criteria for judging the grade of the bolts, both of which are available in destructive tests by SGS and TUV.

The Grade-12.9 2023 Audi Q3 wheel bolts have an ultimate tensile strength of 1282MPa and proof load of 121,000N, while the forged titanium 2023 Audi Q3 wheel bolts have an ultimate tensile strength of 1110MPa. Both allow the vehicle to remain safe during long or aggressive driving. The strength ratio of titanium alloy is close to Grade-12.9 wheel bolts, but many track day players favor its lightweight feature.
