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

Flat spacer washer for helicopter hardware

Listed among Hirobo general helicopter components, this flat washer carries the model code HI2506020 and the dimensions 5 x 10 x 1T as stated in the title. It functions as a uniform thin spacer placed between fasteners and adjoining parts in small-scale assemblies.

Commonly the washer is used to set axial clearance, reduce metal-on-metal contact, and help preserve correct preload on bearings and shafts. Its slim profile makes it suitable as a shim when fine dimensional correction is necessary during setup or servicing.

Practical fitting steps: clean all contact surfaces, test-fit the washer over the bolt or shaft for correct seating, and assemble ensuring the washer lies flat. When adjusting stack height, add or remove one washer at a time and recheck movement of linkages and bearings after each change.
