Running out of the right screw size mid-project — or hunting through multiple bags to find a matching washer — wastes time and breaks workflow. This 200-piece aluminum alloy countersunk screw and washer assortment set gives you a ready-to-use selection of anodized flat head Allen screws and matching washers in a coordinated gold-to-burgundy color range, all organized in a clearly labeled see-through storage box.
Each screw is machined from high-strength aluminum alloy with an anodized surface treatment for excellent corrosion resistance and rust prevention. The flat countersunk head seats flush with or below the surface of the material for a clean, low-profile finish. The internal Allen (hex socket) drive allows precise torque application with a standard hex key. Washers are included to distribute clamping load and protect surface finishes. The full set spans a gold-to-burgundy anodized color range, making it ideal for color-coordinated precision builds.
This countersunk screw and washer assortment is widely used in aerospace industry components, aviation and RC model toy accessories, high-end aluminum alloy bicycle frames, golf club heads, mechanical equipment, mold processing, computer accessories, and general DIY precision builds where a lightweight, corrosion-resistant, flush-mount fastener kit with organized storage is needed.
Keep a ready-to-use assortment of lightweight aluminum countersunk screws and washers on hand for FPV frames, RC airplane builds, and aviation model accessories where multiple screw sizes are needed across a single build.
Ideal for high-end aluminum alloy bicycle frame assembly and golf club head builds where a selection of flush-mount countersunk screws and washers in a coordinated color range is needed for both structural performance and a clean, professional finish.
Suitable for mechanical equipment assembly, mold processing, and computer accessories where having an organized assortment of aluminum countersunk screws and washers on hand reduces downtime and eliminates the need to order individual sizes for every job.
Perfect for any DIY workshop, maker space, or custom build environment where a well-organized, color-coordinated countersunk screw and washer kit adds both practical utility and a clean, professional aesthetic to finished projects.

Yes. Both the countersunk screws and the washers in this set are made from aluminum alloy with an anodized surface treatment, consistent with the gold-to-burgundy color range of the full set.
These screws use an Allen (hex socket / internal hex) drive. A standard hex key (Allen key) in the appropriate size for each screw is required for installation.
Yes. Countersunk screws require a matching countersunk (chamfered) hole in the material to allow the tapered flat head to seat flush with the surface. A countersink drill bit at the appropriate angle (typically 90°) is used to create the countersunk recess before installing the screw.
Yes. The see-through storage box is durable and sturdy, designed to be reused for ongoing storage of the screws and washers between projects. The clearly labeled compartments make it easy to identify and access the size you need without emptying the box.
Yes. Aluminum alloy is significantly lighter than steel — typically about one-third the weight for the same volume. This makes these screws well-suited for weight-sensitive applications such as RC models, aviation accessories, and bicycle frames.
The anodized finish is integrated into the surface of the aluminum rather than applied as a paint or coating, making it generally more resistant to fading and chipping than painted alternatives under normal use conditions.
