Kyosho Grub M4x10 RC Screw - 1-S54010

The Kyosho M4x10 grub screw (KYO1-S54010) is a pack of six metric set screws used for securing components on Kyosho RC cars and compatible builds. Grub screws of this type are commonly used to lock motor pinions, drive cups, wheel hubs, and similar rotating or sliding components in place. Having a supply of these M4x10 fasteners on hand is practical for routine maintenance and repairs, as they are small parts that can strip or go missing during regular servicing.

Key Features

• M4 thread with 10mm length — a common metric fastener size used across a wide range of Kyosho RC car assemblies
• Six screws per pack, giving you spares for multiple components or future servicing needs
• Grub screw (set screw) design with no external head, allowing flush or recessed installation where clearance is limited
• Suitable for applications such as pinion gear retention, drive cup locking, and hub fixing on compatible Kyosho models

What's Included

• 6 x Kyosho M4x10 grub screws (KYO1-S54010)
