3RACING 3RAC-WC4/BU Blue Aluminium M4 Countersink Washers (10 Pack)  [3RAC-WC4/BU]

3RACING 3RAC-WC4/BU Blue M4 Countersink Washers for Precise Builds

The 3RACING Aluminium M4 Countersink Washer in blue is a handy upgrade for hobbyists who want tidy screwwork and consistent fitment. These washers sit under countersunk heads to deliver a flush surface, helping reduce snagging and keeping body panels and components neatly seated. Machined from aluminium, they balance strength with low weight for everyday use on track or practice rigs.

Uses and Fitment Notes

These M4 countersink washers suit a wide range of RC models where a clean profile is wanted. They are especially useful for builders who take gear apart regularly, as they stop screw heads from sticking out and help keep assemblies aligned during rebuilds. The neat finish also helps when running on smooth surfaces at higher speed.

Construction and Chassis Compatibility

Made from durable aluminium, these washers resist deformation under normal use and maintain consistent seating over time. They work with standard M4 countersunk screws and fit typical chassis and body mounting locations, making them a useful addition to any RC maintenance kit.
