4 x 22 x 1T Hirobo HI2506030 Thin Flat Washer for RC Helicopter Linkages  [HI2506030]

Thin spacer for rotor and linkage setups

This Hirobo flat washer serves as a compact accessory for helicopter assemblies where a low-profile spacer is needed. The KDC-B plastic keeps the part light while maintaining contact under screw heads or nuts. As a non-load-bearing item, it primarily spreads clamp force and helps preserve alignment at small joints in the model.

To fit, position the washer between the fastener and the mating surface so the bearing area increases and local stress is reduced. In tight rotor head stacks the 1T thickness helps avoid interference with blade or control travel. Always confirm seating and clearance once installed and swap out any washers that show deformation.

Setup tip: use this washer to tweak spacing on control linkages without changing screw length. Because it is plastic, avoid excessive torque which can crush or shear the washer; include it in routine inspections during model setup and maintenance.
