Hirobo HI2506025 8 x 15.5 x 1.6 Flat Washer for RC Helicopter Use  [HI2506025]

RC helicopter hardware: flat washer details

This RC-scale flat washer carries the Hirobo part number HI2506025 and is listed as 8 x 15.5 x 1.6 for identification. It is intended for general use in helicopter spare parts where a thin spacer and a flat bearing face are needed in compact assemblies.

The washer acts as a spacer and helps to spread load between fastener heads and mating components, which assists in stabilising preload and reducing wear on softer materials. It is useful to keep this component among routine maintenance spares for small repair tasks and light rebuilds requiring exact-fit washers.

Fitment notes: ensure the washer inner and outer diameters match the bolt and seating geometry before reuse, install the washer flat against the mating surface, and replace it if you observe bending or corrosion. This description is limited to RC helicopter applications and does not imply suitability for other uses.
