Automotive products refer to a wide range of products, from those used for daily maintenance to tools used for repairs. There are many types of automotive products, and they can be broadly divided into seven categories, such as safety parts for enhancing the safety of vehicles, in-vehicle electrical products such as audio, body products such as seat covers and floor mats, etc. Detergents used in car washing are also automotive supplies, and tools for tightening nuts on car tires are also included. In addition to maintenance when a car breaks down, there are racks and car stoppers used to organize tools and automobile supplies used during vehicle inspections, such as when changing engine oil. Because the size of parts differs depending on the type of vehicle, and there are materials suitable for different applications, it is necessary to select the purpose of use clearly.
