TAMIYA TRF 416 Differential Fastener Kit 416-10B by 3Racing  [416-10B]

Diff fastener summary

The 416-10B set from 3Racing is offered as a replacement hardware pack for the TAMIYA TRF 416 differential unit, aimed at regular maintenance and correct reassembly of diff internals.

Designed for model-scale servicing, the kit restores secure fastening where screws have worn or been damaged, helping maintain correct part alignment when rebuilding the differential and supporting consistent preload when adjusting the unit.

Fitment advice: disassemble the TRF 416 differential following the service steps, retain and transfer internal bearings and gears as needed, then fit the new screws with even torque to avoid misalignment. Confirm free rotation of the diff after rebuild and avoid over-tightening small screws to preserve thread life.

Workshop note: replacing fasteners as part of oil or shim changes keeps reassembly consistent and reduces variables when you are tuning differential action on the TRF 416.
