3RACING M3 Black Aluminium Flat Washer Set 4.0mm 10pcs - 3RAC-WF340/BK  [3RAC-WF340/BK]

Engineered Flat Washers for RC Maintenance

For hands-on modelers, the 3RACING Aluminium M3 Flat Washer 4.0mm in black delivers straightforward improvements to fastening points. These washers help spread loads and preserve both metal and plastic mounting surfaces during regular use.

Why Aluminium Works Well

Aluminium is chosen for its light weight and resistance to rust, which makes it practical for trimming unsprung mass while keeping fittings reliable. The M3 dimension is a common match for many RC assemblies.

Where to Fit These Washers

They suit tasks like shimming suspension pivots, securing lightweight body mounts, or spacing electronics anchors. At 4.0mm thickness they give predictable spacing and stronger clamping where needed.
