Trim Screw Heads with 3RACING 3RAC-WC4/BU Countersink Washers

The 3RACING Aluminium M4 Countersink Washer in blue helps achieve a neat, low-profile finish on exposed screws. Fitted under countersunk heads, these washers reduce protrusion and maintain a smooth exterior on body panels and mounts. Their aluminium build offers a balance of lightness and resilience suited to hobby use and track days.

Suitable Applications for Model Builders

These M4 countersink washers are useful for chassis, body mounting, and accessory fitting where a clean surface is important. They assist builders who frequently service their models by preventing screw heads from catching and making reassembly easier. A smooth outer profile can also help marginally with aerodynamics at speed.

Material and Compatibility Overview

Crafted from aluminium, the washers resist common wear and provide secure seating for countersunk screws. They are compatible with standard M4 countersunk fastenings and fit most mainstream RC mounting points, making them a practical spare for any toolkit.
