The HUDY 296542-C wheel nut is a purpose-made RC wheel fastener: a titanium M4 nut that incorporates a serrated flange, supplied in a set of 4 pcs with a rainbow-style finish. The serrated flange forms a mechanical lock against the wheel face to reduce back-off caused by vibration.
These nuts are sized for M4 threaded studs commonly used on many 1/10 and similar scale wheel hubs. Titanium gives a combination of lower weight and improved fatigue performance relative to standard steel, so the hardware contributes minimally to unsprung mass while increasing longevity.
To fit, run the nut onto the M4 stud until the serrated flange meets the wheel surface, then apply the appropriate driver to achieve final torque and ensure proper flange engagement. It is good practice to verify and retorque after initial running as part of standard upkeep.
A concise, reliability-focused wheel fastening alternative for modelers seeking the benefits of titanium and a serrated flange locking feature for secure wheel retention.
