Technical Performance
These set screws are engineered to withstand the demanding requirements of modern RC racing and bashing. The M3x3mm specification represents a critical fastener size used throughout the ARRMA product range, from the compact 1/16 scale Mini Kraton through to the powerful 1/5 scale eight-cell LiPo-powered Kraton and Outcast models.
