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

Slim flat washer for RC helicopter assemblies

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 function is purely mechanical in model assemblies, supplying a thin, consistent spacer between fasteners and mating parts.

In typical use the washer helps set axial clearance, stops direct metal-to-metal contact, and keeps correct preload on small shafts and bearing interfaces. As a thin shim it is useful when small dimensional corrections are needed during setup or routine maintenance.

Installation notes: clean mating surfaces first, slide the washer onto the shaft or bolt to confirm fit, and assemble so the washer sits flat and undistorted. For fine tuning, add or remove a single washer to change stack height in small increments, then check that linkages and bearings move freely.
