Tamiya TT-01 Replacement M3 x 18 Step Screw Heavy Duty for TT-01 TYPE E - TT01-10/HD by 3Racing  [TT01-10/HD]

Sturdy M3 x 18 step screw for TT-01 platform

This M3 x 18 step screw is supplied as a direct replacement for Tamiya TT-01 and TT-01 TYPE E chassis assemblies. The stepped design locates plates and brackets without extra spacers, simplifying installation and improving repeatability.

Use on the specified models only; the screw is a heavy-duty steel upgrade to standard hardware where increased clamping reliability is needed for assembly, servicing, or setup changes.

Fitment advice: use the correct hex driver for the screw head, ensure components are aligned before tightening, and apply steady, moderate torque to avoid thread damage on plastic or composite chassis parts. Verify tightness after a short run and after initial break-in for stable setup results.

Setup impact: upgrading to heavier step screws can reduce hardware deformation, which helps keep suspension mount and gearbox alignment steady during tuning and track sessions.
