TAMIYA M03/M03M/M04M/M05/TT01 Step Screw Type E Heavy Duty - M03M-19/HD by 3Racing  [M03M-19/HD]

Type E heavy-duty step screw for TAMIYA race and club chassis

This 10-piece pack contains Type E step screws intended for RC TAMIYA chassis, listed as part M03M-19/HD. The screws serve as heavier-duty replacements for stock Type E hardware on M03, M03M, M04M, M05 and TT01 platforms to help strengthen mounting points and support setup changes during maintenance or event prep.

Fitting is simple: verify thread engagement and the stepped length match the mounting hole, use the correct hex driver to prevent head damage, and tighten to sensible torque for small-scale RC fasteners. For consistent setups check mating threads and clean contact surfaces before final assembly, and use a medium-strength thread locker if you want longer-term security.

Keep this pack in your pit kit as a direct swap when originals wear or as a matched set for repeatable tuning changes and roadside fixes.
