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

Thin flat washers for helicopter maintenance

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.
