4mm flanged fastening part for F1 and Group C

This replacement nut is intended for Tamiya F1-type builds and compatible F101/102 Group C hop-up assemblies. The flange gives a broader seating area to help spread load and resist loosening on vulnerable points such as suspension anchors and body mounts.

Apply this nut where the original component calls for a 4mm flange nut in F1 chassis or Group C hop-up setups. It is designed for part swaps, routine upkeep, and small adjustments like securing linkages or fixtures following setup changes.

Installation notes

Mount only on matching 4mm threaded studs and check that threads engage properly before applying final torque.
Hand-start the threading to prevent cross-threading, then use a correctly sized hex key or wrench to finish.
Avoid excessive tightening; thin panels and plastic mounts can deform under too much torque.
Re-inspect and re-torque after initial use and during scheduled maintenance to ensure continued retention under vibration.

Will this nut fit non-Tamiya F1 kits with 4mm studs?

It will fit any chassis or hop-up kit that uses standard 4mm threaded studs and matching clearances; always confirm stud diameter and thread engagement for the specific model.

Can the flange cause interference with nearby parts?

The flange is low-profile but may need clearance if mounted close to tight panels or recessed fixtures; check fitment before final assembly.

What inspection should I do after fitting?

Verify full thread engagement, ensure the flange seats evenly, then perform a short run and re-check the nut for any loosening or movement.
