The M4 Aluminum Lock Nut is designed as a lightweight and durable upgrade part for 1/10 RC model cars. Made from aluminum alloy with an anodized surface finish, it provides a good combination of strength, corrosion resistance, and reduced weight for RC applications.
The built-in nylon locking insert helps resist loosening caused by vibration during driving, making it more secure than a standard nut. The integrated flange design provides a wider contact surface, helping distribute clamping force more evenly during installation.
With an M4 thread, approximately 7 mm hex width, 6 mm overall height, and 10 mm flange diameter, the nut is suitable for compatible RC wheel and chassis fastening applications. It is available in multiple anodized colors including Light Blue, Blue, Green, Purple, Red, Gold, Orange, Silver, and Black.
Each set includes 4 pcs, making it a practical replacement or upgrade option for compatible HSP 1/10 RC models and other RC vehicles using the same M4 specification.
