Hirobo HI2506025 8 x 15.5 x 1.6mm Flat Washer for Helicopter Servicing  [HI2506025]

Compact flat washer for helicopter model assemblies

This RC flat washer is supplied under the Hirobo part number HI2506025 and recorded as 8 x 15.5 x 1.6 for reference. It is intended as a general hardware item in helicopter spare-part kits where thin spacing and a flat bearing surface are needed in confined assemblies.

Used as a spacer and load spreader, the washer distributes forces between fastener heads and mating parts, helping to maintain preload and to limit wear on softer components. Keep a few spares for routine maintenance, quick repairs, and minor rebuilds that require precise washer thickness.

Fitting advice: confirm the washer inner and outer diameters match the bolt and seating geometry before reuse, fit the washer flat to the mating surface, and replace it if any bending or corrosion is present. This description is confined to RC helicopter use and does not imply suitability for non-model applications.
