3RACING 3RAC-WC4/LB Light Blue M4 Countersink Washers 10 Pack  [3RAC-WC4/LB]

Secure Mounting with Light Blue Countersink Washers

The 3Racing aluminium M4 countersink washer in light blue is a straightforward upgrade for tidy hardware and better screw seating. These washers help keep screws flush and reduce the chance of them catching or working loose while running.

Common Applications in RC Builds

These washers suit areas where low profile mounting is needed, such as chassis seams, radio trays and body mounts. The countersink form provides a neat finish while the colour helps when swapping parts pitside.

Compatibility Notes for Hobbyists

Made to match typical M4 fittings used on 1/10 scale RC cars, these washers are handy for both new assemblies and routine maintenance. They are especially useful in high-vibration setups to help maintain clamp force.
