Tamiya 54421 Titanium Round Head Socket Screws - F104 RM-01 Fitment  [54421]

High Strength, Low Weight Titanium Screws

Fit Tamiya 54421 titanium round head socket screws to reduce weight without sacrificing durability. These 2x5mm titanium fasteners are made to replace stock steel screws and are especially useful when securing side links on the RM-01 and Formula One F104 ver.II chassis kits, helping to sharpen steering response.

Why Titanium Helps Handling

Titanium delivers a superior strength-to-weight ratio compared with regular steel, meaning you can trim mass in sensitive areas of the car. Lighter fastenings can improve transient response and make the car feel more agile on tight circuits.

Sized for Side Links and Connector Points

The 2x5mm dimension is matched to the side link fixings on RM-01 and F104 chassis. For components like the RM-01 servo saver and front uprights that use ball connectors, 2x8mm screw options are available to maintain secure attachment points.
