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

Robust step screw engineered for TT-01 chassis

This M3 x 18 step screw is a replacement fastening part for Tamiya TT-01 and TT-01 TYPE E chassis. The stepped shoulder helps locate chassis plates and mounts without extra washers, giving a cleaner assembly and repeatable positioning.

Compatibility is limited to the models named in the product title, and this item is offered as a heavy-duty steel option to replace lighter hardware when you need improved clamp strength during build, repair, or setup changes.

Installation tips: fit the correct hex driver to the screw head, line up components before engagement, and apply moderate torque to avoid stripping threads in plastic or composite chassis parts. Recheck screw tightness after a short shake-down run and following initial break-in for consistent setups.

Tuning benefits: swapping standard fasteners for heavier step screws can reduce head deformation and help maintain alignment of suspension pivots and gearbox interfaces under load, aiding more consistent handling during practice and adjustments.
