Hirobo HI2506063 Flat Washer 4x7x1T for Helicopter Maintenance  [HI2506063]

Helicopter flat washer application

This Hirobo HI2506063 flat washer is an RC-scale accessory intended for use in helicopter maintenance and assembly tasks. The part is identified by its 4x7x1T designation which denotes its nominal inner diameter, outer diameter, and thickness as listed by the manufacturer name and model number.

Common use cases include acting as a thin spacer or a load-distributing washer in rotor linkages, frame joints, and other fastener points where precise spacing preserves alignment. In tuning situations the washer helps control play and keeps consistent contact between mating parts without altering core geometry.

Installation advice: confirm the washer fits the intended bolt or shaft and verify clearance around nearby hardware before final assembly. The washer should sit flat and must not cause bending on fasteners. Replace any washer that shows deformation or heavy wear to maintain reliable fastener performance in RC helicopter systems.
