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

Compact 4mm flange nut for tuning and repairs

This nut is a practical replacement for Tamiya F1-style configurations and compatible F101/102 Group C hop-up parts. The flanged design helps distribute clamping pressure and reduce loosening on vibrating joints like suspension linkages and lightweight mounts.

Install this nut where your assembly specifies a 4mm flange nut for F1 chassis or Group C hop-up hardware. It is intended for maintenance, part swaps, and small tuning tasks such as locking down linkages or securing body fixtures after adjustments.

Installation notes

• Use only with matching 4mm threaded studs and ensure correct thread engagement before final torque is applied.
• Thread the nut on by hand first to avoid cross-threading, then tighten with a correctly sized hex driver or spanner.
• Do not overtighten; check mating plastics or thin panels to prevent crushing or deformation.
• Inspect and re-torque after the first outing and periodically as part of routine checks to keep components secure under vibration.
