The RADTEC 3x5.5x0.5mm Aluminum Spacer set gives hobbyists a neat way to dial in clearances on models. Each shim is made from anodized aluminum in orange and supplied as a pack of ten for consistent use across multiple service jobs.
Designed for assemblies needing a 3mm ID spacer, these shims are useful when precise 0.5mm increments matter, such as between gear faces or under suspension mounts. The matched thickness across all ten ensures predictable results when swapping or stacking pieces.
Beyond the visual appeal, the anodized coating helps protect the aluminum and reduces surface wear during repeated assembly. The material keeps weight low while offering good resistance to corrosion in hobby environments.
