Why Are There Paint Marks on New Car Screws?
1 Answers
New car screws having paint marks is a normal phenomenon. The paint on the screws, also known as a seal, is a mark intentionally made by technicians during the original factory assembly of the vehicle, which can also be understood as a mark of the new car. The most obvious function of this mark and seal is to clearly confirm whether the screw has been turned after the original factory assembly. Most of the important components of the vehicle have screws with paint lines. By checking whether the paint marks on the top of the screw and the screw itself are damaged, one can determine if the component has been disassembled. Depending on the location and the model of the car, the color of the paint may vary, but they are generally similar. Some screws that are flush with the body components also have seals. Manufacturers usually spray paint of the same color as the body on these screws, which typically require a cross-head or flat-head screwdriver to remove. When force is applied between the screwdriver and the screw, the paint on the screw will crack or show signs of wear. The paint on the screws can indicate whether the fixed components have loosened. For example, prolonged jolting of chassis components may cause certain parts to loosen. During chassis inspections, repair technicians will refer to the paint marks on the screws to determine which component has loosened.
