3RACING 3RAC-WC4/LB Light Blue Aluminium M4 Countersink Washer Set 10 pcs  [3RAC-WC4/LB]

Quick Fit Countersink Washers for Durable RC Builds

The 3Racing aluminium M4 countersink washer in light blue is a handy part to keep in your toolkit. These washers help screws sit flush with surfaces and add a small measure of protection against wear and vibration, which helps keep assemblies tight during running.

Where These Washers Work Best

Use these lightweight aluminium washers on areas where screw heads need to sit flush, such as chassis plates and body mounts. The countersunk profile gives a neat finish and the light blue finish makes it easier to spot hardware during trackside repairs.

Scale Compatibility and Vibration Control

Made for broad compatibility with 1/10 scale RC models, these M4 washers are useful both when building a new kit and when upgrading hardware to resist high-vibration conditions. They provide a simple way to improve reliability without adding significant weight.
