The Tamiya 10307 AO-1036 2mm spring washer set is a practical spare parts pack for Mini 4WD fans. These spring washers are intended to keep screws and bolts secure on both standard and PRO series cars, helping to maintain reliable assemblies during practice and club racing.
These 2mm washers suit many Tamiya Mini 4WD chassis types and are useful when rebuilding or upgrading your car. They sit beneath screw heads to add tension and minimise loosening on bumpy tracks.
Spring washers reduce the chance of components loosening from vibration during high-speed laps. That means fewer pit stops for tightening and a steadier setup across multiple runs.
