This is an M 3.5x10 hex socket tapping screw sized for RC use, useful for replacement and maintenance where a self-tapping fastener is needed. It provides improved thread engagement in plastic components and thin alloy parts that are common in model assemblies.
Fitting is straightforward: line up the parts, use an appropriate hex driver, and apply torque carefully to avoid damaging softer materials. Because the screw cuts its own mating thread, pre-drilling is generally not required for typical RC plastics, though very hard materials may benefit from a pilot hole for best results.
In service these screws help secure chassis plates, bracketry for electronics, servo mounts, and body posts. Attention to correct torque and inspection after repeated removal will help maintain component integrity over time.
