What is the use of it?
Fastening: Provides secure attachment of panels, covers or trim pieces to the body or other panels.
Easy Removal-Attachment: Thanks to its clip-on structure, it allows the panels to be easily removed and installed during repair or maintenance operations.
Aesthetics: It ensures that the parts remain in place without spoiling the appearance and offers a cleaner appearance compared to screw connections.
These types of snaps may be called by this specific name because they are used in certain models, particularly by brands like Alfa Romeo. However, the general principle is the snap/clip fastening system commonly used in vehicles.
