Yokomo ZC-B320TT M3x20 Titanium Tapping Hex Screw  [ZC-B320TT]

Light titanium tapping screw for drift chassis

This RC-scale tapping screw is sold as the Yokomo ZC-B320TT and is intended for use with the Drift Package series. The M3x20 designation in the model name denotes the nominal thread size and length used for standard RC tapped mountings.

Manufactured from titanium, this fastener reduces mass and offers better corrosion resistance than common steel hardware, making it a good choice for chassis mounting points and body-fixings where lower weight and environmental durability matter. It installs into pre-tapped M3 holes and serves as a direct replacement where the Drift Package series specifies M3 tapping hardware.

From a tuning perspective, fitting a titanium tapping screw like this trims marginal unsprung and rotating weight and eases upkeep in humid or seaside club environments. Start threads carefully to avoid cross-threading and use appropriate tightening practice on aluminium or composite mating parts to avoid damage.
