DIYers and mechanics, these M4 cone cup washers are seriously handy for all kinds of projects! Made from 6061 aluminum alloy with a beautiful purple anodized finish, these washers are not only functional but look awesome too. The anodic oxidation surface treatment makes them waterproof, rust-resistant, and corrosion-resistant, so they'll hold up well in various environments. The CNC machining gives them a smooth surface and bright, consistent color that won't fade or chip easily. Each washer weighs just 0.51 grams, so they're lightweight without sacrificing strength. The cone cup design is perfect for countersunk applications where you need a flush finish, and the M4 size works with standard metric hardware. With 50 pieces in the package, you've got plenty for multiple projects or replacements down the road. The quality is impressive - precise dimensions, clean edges, and durable construction that feels substantial. Whether you're working on RC cars, 3D printers, furniture assembly, or any project requiring reliable hardware, these washers deliver both performance and style. The purple color makes it easy to identify specific fasteners in complex assemblies, which is super helpful for maintenance or repairs. If you're tired of basic silver washers and want to add some color and quality to your projects, these anodized aluminum washers are a game-changer. They're one of those small components that show you pay attention to details and care about both function and aesthetics in your work.
