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.
They provide a simple upgrade path: retain existing hubs and wheel adapters while swapping to titanium fixings that resist corrosion and wear. The result is a durable, lightweight fastening option for frequent track or club sessions.
To fit, thread the nut onto the M4 stud and bring the flange flush with the wheel or adapter surface. Tighten evenly until the serrations engage; do not overtighten beyond the hub or wheel supplier's recommended limits.
A practical, performance-conscious replacement for M4 wheel fixings where anti-loosen behavior and corrosion resistance are desired for regular on-track or club driving.
