This HUDY titanium M4 serrated flange nut set is an RC-scale wheel fastening item supplied as a set of 4 pcs, intended for models that use M4 threaded wheel mounts. The serrated flange increases contact against the wheel surface to resist gradual loosening from vibrations typical in club and track driving.
In practical terms these nuts serve a straightforward tuning and maintenance role: they secure the wheel to the hub while offering corrosion resistance and longevity from the titanium construction. Use them when replacing worn wheel fixings or when upgrading to a lighter, more durable fastening option without changing hub hardware.
Installation is simple for any builder familiar with RC wheel service: thread onto M4 studs, seat the flange fully against the wheel or adapter, and tighten progressively until the fit is firm and the serrations engage the mating surface. Avoid over-tightening beyond the hub or wheel manufacturer’s recommendations.
A technical, small-form upgrade for M4-threaded RC wheels where durable, anti-loosening fastenings are needed, suitable for track day use and routine tuning work.
