This black 4mm hex post set is produced as a compact spare for Tamiya Mini 4WD cars. The posts offer the common 4mm hex mounting interface used to secure rollers, stabiliser brackets, and bumper fittings on standard Mini 4WD chassis. The black finish is chosen to match usual aftermarket metal parts and stock plastic components.
Designed for compatibility with mainstream Tamiya Mini 4WD assemblies; builders should measure post diameter and thread compatibility against their rollers or mounting plates before fitting. The parts are intended as replacement mounting posts rather than performance-enhancing upgrades, and they are fitted with standard screw assemblies.
Best suited to seasoned hobbyists as service spares for repair, refurbishment, or neat custom builds where a consistent hex interface and finish are needed. Avoid expecting added performance on non-compatible series.
