The Tamiya 49163 Countersunk Washer Set is built to give a low profile fastening option for RC models. When used with hex screws the washers reduce visible screw heads and help shield mounting zones from wear. This set is well suited to both quick repairs and modest performance tweaks around the workshop.
These countersunk washers are formed to sit correctly with hex-headed screws across common mounting patterns. They assist in keeping fasteners tight while evening out pressure across the part surface, which helps preserve the integrity of assemblies under load.
