The Tamiya 9803406 Cs Screw is designed as a general spare for scale R/C models, useful when adjusting or reassembling parts during tuning. The unit is a CS Screw at 4x42mm with a Phillips head, suitable for standard fastening tasks on both chassis and bodywork.
Install this screw to replace missing or worn fasteners during setup, or when securing accessories that are not load-critical. Common uses include fixing servo mounts, body posts, and accessory brackets on scale R/C vehicles.
Tuning tip: use the correct Phillips driver to prevent cam-out, apply moderate torque settings, and keep a mix of common screw sizes available so you can swap fasteners quickly between runs.
