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

Titanium tapping screw for drift builds

This RC-scale tapping screw is offered under the Yokomo ZC-B320TT designation and is intended for use with the Drift Package series. The M3x20 form factor in the model name indicates the nominal thread and length convention used for typical RC tapped mountings.

Made from titanium, the fastener targets reduced mass and enhanced corrosion resistance compared with standard steel hardware, making it suitable for chassis areas and body-mount points where lower weight and environmental durability are priorities. It installs into pre-tapped M3 holes and functions as a direct replacement where the Drift Package series specifies M3 tapping hardware.

In practical tuning terms, using a titanium tapping screw like this helps keep unsprung and rotating component weight down at the margins and can simplify maintenance in humid or coastal club environments. Take care to start threads cleanly to avoid cross-threading and to use the proper tightening practice for tapped aluminium or composite parts to prevent damage to the mating material.
