Flat Spacer Washer 2 x 3.8 x 0.3T HI2506062 by Hirobo  [HI2506062]

Durability and fitment notes for small hardware

The Hirobo flat washer HI2506062 carries the dimensional code 2 x 3.8 x 0.3T and is intended as a slim spacer where that precise size is required. It provides a seating surface to spread clamping load and preserve consistent clearance between fastener heads and mating parts in helicopter model builds and other compatible electric RC models.

When installing, position the washer directly under the bolt head or nut to stabilise the joint and reduce localised stress. For assembly adjustments the washer helps maintain repeatable spacing so linkages and gear engagements remain predictable after rebuilds.

Service advice: inspect the washer for bending, bore elongation or surface damage during routine checks; replace any washer that shows deformation to keep joints reliable under repeated torque cycles.
