Race-focused countersink washers for consistent clamping

The 3Racing Light Blue Aluminum M3 Countersink Washer Set 3RAC-WC3/LB is intended as a simple, cost-effective part for setup consistency. Manufactured in aluminium, the washers keep mass low while providing a stable seating surface for M3 fasteners. The light blue finish aids quick identification during setup changes.

Why fit countersink washers in a race setup

These washers support repeatable screw torque and reduce movement at the joint, which helps maintain alignment and handling across runs. The M3 size is compatible with common race chassis hardware, making them suitable for routine tuning and component swaps.

Tuning and maintenance considerations

Fit the washers where you need uniform clamp distribution or where countersunk heads risk deforming softer materials. They are a pragmatic upgrade for improving serviceability and preserving part fitment under frequent teardown and rebuild cycles.

Will these affect ride weight significantly?

No, the aluminium construction is lightweight and will have a negligible impact on overall model mass while improving seating consistency.

Are they useful for repeated teardown?

Yes. They help preserve hole edges and provide a consistent seating surface across multiple service cycles, aiding repeatable rebuilds.

Do they work with thread locker?

You can use removable-grade thread locker if needed; avoid permanent grades that make future adjustments difficult and risk damaging the washer or mating part.
