For hobbyists who value clean installs, the 3Racing Aluminium M4 Countersink Washers provide a low-profile solution that keeps screw heads below surface level. They work with countersunk fasteners to reduce catches and maintain smooth body lines.
Lightweight aluminium helps keep overall model mass down without sacrificing local strength around screw points. The red anodising adds a layer of protection against moisture and wear while offering a neat visual accent.
These washers are matched to M4 countersunk fittings and are useful for securing body shells, mounting brackets, or any components that require a flush outer surface.
