TRF421 3x6mm Countersunk Flat Screw - Tamiya 9803568  [9803568]

Flat 3x6mm screw for TRF421 applications

This Tamiya replacement screw is intended for use with TRF421 hop-up assemblies and related small component mounting. It matches the flat-head 3x6mm profile commonly referenced in TRF421X kits and hop-up packs.

Use and role: These flat screws act as retention hardware for chassis plates, shock tower mounts, gearbox brackets and other compact assemblies on TRF421-compatible builds. They are useful for routine maintenance, replacing lost fasteners, and keeping tuned parts secured during setup changes.

Installation notes: Fit into original threaded bosses or compatible replacement inserts and tighten until snug without over-torquing; ensure mating parts are aligned before final tightening to preserve thread engagement and correct positioning.
