This Hirobo flat washer HI2506026 is an RC-scale accessory intended for use in helicopter general parts where thin spacing or shim adjustments are required. Supplied as a pair, each item helps maintain consistent gaps between mating components and supports repeatable reassembly during maintenance or setup.
Practical use: fit these thin washers when you need controlled, uniform spacing for rotor head linkages, frame fittings, or other compact assemblies where precise clearance affects alignment and control feel. The listed dimension (14 x 18.5 x 0.5T) defines inner and outer sizing and the slim profile used for fine adjustments rather than heavy load support.
Installation tip: slide the washer onto the bolt or shaft until it seats against the mating surface, check alignment, and torque fasteners to the component maker's recommended values. When stacking multiple washers, measure the total thickness before final assembly to avoid unwanted preload on bearings or changes to linkage geometry.
