3x6x1.5mm Red Anodized Aluminum Shim Collars 8pcs - Yokomo YOKZCRA3615  [YOKZCRA3615]

Compact anodized shim collars

This pack contains eight 3x6x1.5mm aluminum shims/collars in red manufactured by Yokomo, intended as small, precise spacers for hobby R/C models. The rings are intended to sit where a thin, rigid shim is required to correct wheel spacing, centre an axle, or take up a small amount of lateral play in assemblies that accept a 3x6x1.5mm washer-style part.

The anodized aluminum construction resists corrosion better than plain metal washers while remaining lightweight. The red finish makes individual collars easy to spot when organising parts during a build or setup session.

Fitment is simple when the mating parts allow a 3x6x1.5mm shim: position the collar on the shaft or between hub surfaces as needed, then reassemble the related components. Follow standard workshop checks to confirm free movement and to prevent binding; remove the original part for a trial fit if clearance is uncertain.

For setup and small tuning changes, single or multiple collars can be stacked to tweak track width, alter bearing preload, or remove slight axial slack without modifying larger components. Keeping extra collars is a low-cost way to experiment with fine geometry changes.
