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

Precision 5 x 10 x 1T flat washer for model helicopters

This washer is catalogued as a Hirobo general helicopter part, model HI2506020, with the size marking 5 x 10 x 1T reflected in the product title. It serves as a simple mechanical spacer, providing a uniform thin layer between fasteners and mating components.

Functionally, the washer is useful for setting small axial gaps, reducing direct contact between metal surfaces, and preserving correct preload on bearings and shafts. Due to its slim profile it is commonly employed as a shim when minute dimensional adjustments are required during setup.

Fitment tips: wipe mating surfaces clean, trial the washer on the bolt or shaft to ensure smooth seating, and assemble so the washer lies flat without distortion. For tuning adjustments, change stack height one washer at a time and recheck linkages and bearing freedom after each change.
