This is the real deal – a GM Genuine Parts multi-purpose rivet, part number 12558759. It's the exact same part that was installed at the factory on your GM vehicle. Used in various places like interior trim panels, wheel well liners, underbody covers, or exterior moldings. These plastic push rivets are designed to hold securely but can be removed (usually with a trim tool) without damaging the panels. GM engineers design and test these parts to fit perfectly and withstand vibration, temperature changes, and general wear. If you're doing repairs or mods on your Chevrolet, Buick, GMC, or Cadillac, using genuine GM parts ensures everything goes back together right. Keep a few in your garage for those times when a clip breaks during a simple project. It's a small part, but using the correct OEM rivet can make a big difference in avoiding rattles or loose panels. Trust the parts that were made for your vehicle from the start.
