For hobbyists focused on setup, the Tamiya 42294 - 3x5mm Step Hollow Screw set helps you fine tune torsional behaviour. These screws let you adjust the damper stay to influence mechanical grip and chassis feel.
Primarily these step hollow screws are used to alter the rigidity of parts such as damper stays, which changes how the model twists under load. Small changes can shift the balance between flexibility and stiffness to suit driving style. They also serve well for securing motor mounts on the chassis, aiding consistent grip and performance.
