Tamiya 70263 8mm Square Plastic Beams 3-Pack  [70263]

8mm Square Tubes for Model Builds

The Tamiya 70263 8mm plastic beams give model makers a straightforward part for extending or modifying RC kits. These square tubes are useful for custom chassis work or creative scratchbuilding and pair well with smaller beam sizes for modular assembly.

Material and Fit Details

Manufactured from polystyrene, these beams balance ease of trimming with durability for hobby use. The internal dimension accepts smaller square beams such as 3mm and 5mm, letting you insert and lock parts together. The square profile helps prevent rotation of inserted elements for cleaner, more accurate assemblies.

Use Cases and Practical Advice

Use these beams to reinforce custom body mounts, build internal frames, or extend booms on scale models. Cut with a hobby knife or thin-blade saw and join parts with Tamiya cement and paints for a tidy finish. They also join directly with other Tamiya beams for larger frameworks.
