Tamiya 54421 Titanium Round Head Socket Screws for F104 and RM-01 Upgrades  [54421]

Lightweight Titanium Fasteners for Precision Builds

Upgrade your RC with Tamiya 54421 titanium round head socket screws. These 2x5mm titanium fasteners replace standard steel hardware to cut weight while adding strength, making them well suited for securing side links on RM-01 and Formula One F104 ver.II chassis kits. The reduced mass helps handling and responsiveness for drivers fine tuning their setup.

Benefits of Titanium Hardware

Titanium offers an excellent strength-to-weight balance compared to ordinary steel fasteners. Swapping to titanium screws can lower rotating and unsprung mass, which may improve acceleration feel and nimble cornering for competitive or hobby track use.

Fitment and Common Uses

The 2x5mm screws are sized for the side links on RM-01 and F104 chassis. If you need replacements for ball connectors on the RM-01 servo saver and front uprights, 2x8mm versions are also commonly offered to ensure secure connections across those parts.
