This item is a GP screw listed under Tamiya model 9400972 and referenced with part code 84067, provided for use with TRF801X scale RC components. It is presented as a replacement fastener intended for hobby-grade model maintenance and tuning, not for any full-size vehicle applications.
Use this screw where the original parts list or component diagram identifies 84067 for TRF801X assemblies. Confirm fit by matching thread size and head style against the part called out in your model's manual before installation. This description restricts itself to the information shown in the product title and part code.
Installation guidance: select the correct driver to suit the screw head, apply steady torque and avoid over-tightening which can strip threads on aluminium or plastic housings, and inspect mating parts for wear before reuse. For repeated removals and refits, consider light thread-locking compound only when the chassis or component design recommends it.
Tuning role: as a fastener, this screw preserves assembly integrity and alignment; maintaining original fastening hardware or using exact replacements helps retain handling characteristics during setup changes on TRF801X scale models.
