The 3Racing Aluminum M3 Countersink Washer Set provides a compact solution to secure M3 fasteners while adding a splash of colour. Lightweight aluminium construction helps keep unsprung mass low where weight matters, and the countersink seats screws flush to the surface.
These washers balance appearance and function, giving mounting points a tidy finish that stands up to regular bashing. The countersink reduces snagging and keeps external surfaces smooth.
M3 compatibility across most RC kits makes these washers an easy swap during maintenance and upgrades. Use them for body posts, electronics mounts, or trim details to personalise your rig.
