Hirobo HI2506020 Flat Washer 5 x 10 x 1T for Helicopter General Parts  [HI2506020]

Flat washer for helicopter parts

This flat washer is an RC-scale accessory listed under Hirobo general helicopter parts, identified by model HI2506020 and the size notation 5 x 10 x 1T as shown in the product name. Its role is purely mechanical within model assemblies, providing a thin, consistent spacer between fasteners and mating components.

In practice this washer is used to adjust axial clearance, prevent direct metal-to-metal contact, and maintain correct preload across small shafts and bearing interfaces. Because it is a thin component it can act as a shim when minor dimensional correction is needed during setup or maintenance.

Installation guidance: clean mating surfaces, slide the washer over the shaft or bolt to check fit, then assemble components in the intended order so the washer sits flat without bending. For tuning, add or remove single washers to change stack height in small increments and verify free movement of linkages and bearings after each change.
