Kyosho Grub M4x8 RC Screw - 1-S54008

The Kyosho 1-S54008 is a pack of M4x8 grub screws (also known as set screws) used across a range of Kyosho RC vehicles and assemblies as a standard hardware fastener. Style code KYO1-S54008 replaces part 1162 in the Kyosho parts catalogue, making it straightforward to identify the correct replacement when ordering. Grub screws of this size are commonly used to secure pinion gears, motor mounts, wheel hexes, and similar components where a flush, headless fastener is required. Keeping a pack of ten on hand means you won't be held up waiting for a single screw when one strips or goes missing during maintenance.
