Hirobo HI2506062 Flat Washer 2 x 3.8 x 0.3T  [HI2506062]

Flat washer for RC helicopter hardware

This Hirobo flat washer HI2506062 is an RC-scale hardware spare listed with its dimensional code 2 x 3.8 x 0.3T, intended as a thin, flat spacer used where that size specification is required. It serves as a basic retention and seating element between fasteners and mating parts in helicopter model assemblies and other electric RC models that accept the same washer size.

Installation is straightforward: place the washer between the head of the bolt or nut and the mating surface to distribute load and maintain consistent clearance. In tuning or maintenance tasks the washer helps keep joint play predictable, so it is useful when small changes in stack height or spacing affect linkage geometry or gear mesh.

Field guidance: confirm the 2 x 3.8 x 0.3T requirement before use, inspect for deformation or wear during routine checks, and replace if the washer flattens or the bore enlarges from repeated torque cycles to preserve reliable fitment.
