3x8x0.5mm Black Aluminum Shim YOKZCA3805B by Yokomo  [YOKZCA3805B]

Durable anodized spacer for RC parts

This Yokomo aluminum shim is a small, precision 3x8x0.5mm washer, listed as model YOKZCA3805B. The black-anodized 0.5mm aluminum provides a wear-resistant surface useful for repeatable spacing where alignment and preload matter.

The shim fits between mating surfaces such as hubs, bearings, or collars to address lateral play or to fine-tune stack height. When combining several shims, measure the combined thickness and ensure there is adequate clearance to avoid shaft binding or contact with moving components.

Designed as a maintenance and tuning aid, the shim is appropriate for common shimming tasks in electric and nitro RC models. Handle and store it with other small parts to avoid loss during rebuilds.
