The clips are made to achieve a snug, rattle-free fit with the ability to be easily removed during repairs or replacement of parts.
Key Characteristics:
o Material: Most commonly plastic (nylon, polypropylene) or metal (steel, aluminum) for toughness.
oDesign: Engineered to snap into pre-drilled holes or onto mounting studs, providing a firm grip without screws or welding.
Molding clips are all-purpose fastening devices applied throughout vehicle assembly to securely fasten trim pieces, moldings, and panels to the automobile body. These minute but vital parts are crucial for vehicle assembly as well as durability after a long period.
