This is a set of 2.5x16.5mm pan head self-tapping screws designed for RC chassis assembly where extra-long reach and strong thread engagement are required. These screws are typically used in deep plastic stack-ups such as chassis-to-chassis connections, reinforced suspension mounts, or structural components that require full penetration through multiple layers of plastic. The self-tapping design allows them to cut directly into molded plastic without requiring pre-threaded inserts, making them useful for repair, replacement, and factory assembly-style fastening. Because of their extended length, they provide higher clamping strength and improved structural rigidity compared to shorter 2.5mm screws. They are less common than standard lengths and are usually found in key load-bearing areas of the vehicle.
