This Hirobo flat washer is an RC-scale replacement part sized 6 x 10 x 0.5 mm and made from stainless steel (SUS). It is intended as a thin flat washer for general RC assemblies where minimal thickness and corrosion resistance are required, such as model helicopter and small aircraft fastenings.
Function: the washer evens load from fasteners, keeps required clearance, and serves as a thin spacer when a 0.5 mm thickness is called for. In model servicing it helps protect delicate parts and maintains alignment during routine adjustments.
Fitting advice: confirm bore sizes and the total stack height before installation, seat the washer flat against the mating surface, and use correct torque to avoid distorting the washer. The stainless build ensures suitability for repeated small-scale maintenance tasks without implying any full-size application.
