Generally, the inspection indicators for fasteners include anti-slip performance and anti-damage performance. Different fasteners have different indicators. According to national regulations, fasteners are considered qualified when they do not fail under a load of P=25KN. However, this standard is far from sufficient for fasteners intended for export. The vehicle inspection process is as follows: 1. Prepare the required materials for vehicle inspection, such as the vehicle license, ID cards of the owner and the agent, and copies of the ID cards. 2. Conduct an exterior inspection of the vehicle upon arrival at the inspection site. 3. Pay the inspection fee and enter the information. 4. Proceed with the online inspection. 5. Undergo a final review by the inspector. 6. Once approved, the relevant personnel will issue the annual inspection sticker to the owner. The inspection cycle varies depending on the vehicle type: 1. For small and micro non-commercial passenger vehicles, inspections are required every 2 years within the first 6 years, annually after 6 years, and every 6 months for vehicles over 15 years old. 2. For commercial passenger vehicles, inspections are required annually within the first 5 years and every 6 months for vehicles over 5 years old. 3. For trucks and large or medium non-commercial passenger vehicles, inspections are required annually within the first 10 years.
