Specifications Type: Specialty Blind Rivet with Plastic Cap Application: Windshield Side Moulding & Gas Filler Cap Material: Aluminum Rivet / Steel Mandrel Rivet Diameter: 3/16" Grip Range: 1/8"–5/16" Flange Diameter: 9/16" Includes: Plastic Cap Vehicle Fitment Toyota — windshield side moulding and gas filler cap applications Cross-Reference Numbers Toyota OEM: 90269-05054 SMS Part#: 20626 What does the plastic cap do? The plastic cap snaps over the set mandrel head after the rivet is installed, concealing the mandrel remnant and providing a clean, finished appearance on visible moulding fastening points. It also helps prevent water ingress through the mandrel hole on exterior applications like windshield and gas filler mouldings. Why is a larger 3/16" rivet used for windshield moulding? Windshield side mouldings and gas filler caps experience more vibration and stress than small interior trim clips. The 3/16" diameter shank and wide 9/16" flange provide greater shear strength and pull-through resistance than a standard 1/8" rivet, keeping larger moulding sections secure over time. Is this an OEM equivalent replacement? Yes. This rivet matches Toyota OEM part number 90269-05054 and is a direct replacement for the factory-installed fastener in Toyota windshield side moulding and gas filler cap applications. How do I install this rivet? Insert the rivet shank into the panel hole, position the moulding, and use a standard rivet gun to set the rivet by pulling the mandrel until it breaks. Snap the plastic cap over the exposed mandrel remnant for a finished appearance. Use a 13/64" drill bit to clean up or create the pilot hole if needed. What pack sizes are available? Available in packs of 25, 50, 100, and 150 to suit single-vehicle moulding repairs or shop stock needs.
