Yokomo Z4-TSS 3mm titanium screw set for YZ-4  [Z4-TSS]

3mm titanium screws for YZ-4

This 3mm titanium screw set is specified for use with the YZ-4 platform and the listed B-YZ4 chassis variant. The set is positioned as a lightweight fastener option intended to replace heavier steel hardware where users want to reduce rotating and unsprung mass on an RC chassis without changing mounting geometry.

Use cases focus on chassis-level tuning: replacing selected mounting screws, reducing weight concentrated at wheel hubs or suspension mounting points, and offering corrosion resistance compared with untreated steel. The material choice targets a balance of lower mass and adequate strength for typical on-track and practice use of 1/10 scale touring cars.

Installation notes: fit screws to original threaded holes without modifying parts, verify threads are clean and free of debris, and perform test-tightening to confirm seating and alignment. When adjusting setups, install gradually and check component clearance and movement before final runs.
