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

Flat washer for model helicopter maintenance

This item is supplied under the Hirobo part number HI2506025 and marked 8 x 15.5 x 1.6 for easy reference. It is designed as a general-purpose washer within helicopter spare-part kits to provide thin spacing and a stable bearing surface in small assemblies.

Functionally the washer works as a spacer and load spreader between bolt heads and mating parts, helping to keep preload stable and to reduce wear on softer materials. Keep spare washers on hand for minor repairs and rebuilds where a precise thickness is required.

Installation guidance: measure the washer outer and inner diameters against the bolt and seat geometry before reuse, install it flat against the mating surface, and replace the washer if you notice bending or corrosion. This note applies to RC helicopter use and does not indicate suitability for other applications.
