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.
Use case: the washer evens load from fasteners, preserves required clearance, and functions as a thin spacer at 0.5 mm thickness. In model maintenance it aids alignment and reduces concentrated stress on delicate components during routine servicing.
Fitting guidance: verify the bore diameter and combined stack height before installation, place the washer flat against the mating piece, and apply correct torque to avoid distortion. As a stainless RC part it is suitable for repeated servicing but is not intended for full-size applications.
