Tamiya F101/102 4mm Flange Nut for F1 Chassis - 9804579  [9804579]

4mm flanged nut for F1-style setups

This compact replacement is made to suit Tamiya F1-style assemblies and compatible F101/102 Group C hop-up components. The 4mm flange nut gives a broad bearing surface to help spread load and resist loosening from vibration when used on suspension linkages, body mounts, and other small fastenings.

Fit this nut where the original specification calls for a 4mm flange nut in F1 chassis or Group C hop-up assemblies. It is intended for model maintenance, part replacement, and light tuning chores such as locking linkages or securing panels after setup changes.

Installation notes

• Only install on matching 4mm threaded studs; confirm full thread engagement before final torque.
• Start the nut by hand to prevent cross-threading, then use an appropriate hex driver or spanner sized for the nut head.
• Avoid over-torquing; thin plastics and light panels can deform if the nut is tightened excessively.
• Check and re-torque after the first run and periodically during routine inspections to maintain retention under vibration.
