Tamiya 9803568 - 3X6mm Flat Screw for TRF421 Hop-Up Parts  [9803568]

3x6mm flat screw for TRF421

This Tamiya replacement screw is an RC-scale hardware item intended for use with TRF421 hop-up assemblies and related small component mounting. The listing references part identifiers associated with TRF421X kits and hop-up packs, making it a direct-fit option where original flat-head 3x6mm fasteners are required.

Use and role: these flat screws serve as basic retention hardware for chassis plates, shock towers, gearbox mounts and other compact assemblies on Tamiya TRF421-compatible setups. They are intended for routine maintenance, part replacement after wear or loss, and for keeping tuned component geometry secure during setup changes.

Installation notes: install into the original threaded bosses or compatible replacement inserts and tighten to a secure feel without over-torquing; confirm alignment of the mating parts before final tightening to preserve thread engagement and component positioning.
