Kyosho Grub M3x3 RC Screw - 1-S53003

The Kyosho M3x3 grub screw (KYO1-S53003) is a small-format set screw used across a wide range of Kyosho RC car builds and repairs. Supplied in a pack of ten, this M3 thread, 3mm length grub screw is a standard hardware item for securing grub-style fittings such as gear hubs, pinion gears, and motor mounts where a flush or recessed fastener is needed. Having a supply of these on hand prevents delays mid-build or after a hard run when a screw strips or goes missing.
