Neat Fit M4 Countersink Washers from 3RACING 3RAC-WC4/BU

The 3RACING Aluminium M4 Countersink Washer in blue gives a clean resolution to protruding screw heads, keeping panels and mounts flush. These washers are simple parts that improve assembly tidiness and help avoid interference during runs. Their lightweight aluminium build keeps mass low while offering practical strength for club and off-road use.

Where RC Builders Use Them

These M4 countersink washers are useful across many RC platforms where a flush finish is preferred, such as touring cars, buggies, and scale bodies. They make repeated disassembly less fiddly by preventing screw heads from catching and help maintain a smooth outer profile that can reduce drag at speed.

Longevity and System Fit

Constructed from quality aluminium, the washers resist wear and provide consistent seating for countersunk screws. They are compatible with common M4 countersunk fastenings and fit into typical mounting points, making them a small but handy part of any tool box.
