Hirobo HI2506037 Flat Washer 10 x 14 x 1T, 5pcs  [HI2506037]

Flat washer for helicopter general parts

This Hirobo flat washer pack contains five identical 10 x 14 x 1T washers intended as RC-scale replacement spacers in helicopter general parts. The set is a simple, low‑cost consumable used where a thin, flat washer is required to set axial clearance, prevent metal‑to‑metal contact, or distribute bolt head pressure on small rotor and gearbox fittings.

Installation notes: confirm the washer bore matches the fastener diameter before use, seat the washer flat against the mating surface, and avoid over‑torquing which can deform thin washers and change clearance. For assemblies that rely on precise preloads, fit washers one at a time and verify free rotation of bearings and gear meshes after tightening.

Tuning role: use these thin flat washers as shims to fine‑tune rotor spacing, align gearbox faces, or remove minor endplay without changing major components. Because the pack includes multiple pcs, keep extras in your maintenance kit for quick on‑field adjustments.
