Standard steel screws add unnecessary weight and corrode over time — a real problem when you’re building custom bicycle frames, RC aircraft, or color-matched electronics assemblies. These M3 anodized aluminum button head screws give you a secure, corrosion-resistant fastening solution with a low-profile rounded head that sits flush and clean against the surface.
Machined from high-strength, heat-treatable aluminum alloy and finished with a durable anodized coating, each screw features a button head profile with a hex socket (Allen key) drive for easy installation and removal. Available in lengths from 6mm to 30mm (M3 x 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 25mm, 30mm) and 9 anodized colors — Royal Blue, Green, Golden, Dark Red, Black, Silver, Purple, Rose Red, and Sky Blue — manufactured to a ±0.3mm tolerance.
These button head Allen screws are ideal for high-end aluminum bicycle frame assembly, drone and RC model builds, aerospace model accessories, computer case modding, golf equipment, mold tooling fixtures, and any precision project where a low-profile, color-matched fastener finish is required.
Ideal for high-end aluminum alloy bicycle frame assembly where a low-profile, color-matched fastener finish and lightweight hardware are equally important.
The lightweight aluminum construction and low-profile button head make these screws a natural fit for RC aircraft, drone frames, and aerospace model toy accessories where minimizing weight and drag matters.
Add a pop of color and a clean flush finish to custom computer cases, cooling systems, and electronics enclosures with anodized button head screws that complement your build’s color scheme.
Suitable for golf equipment, mold processing, mechanical equipment assembly, and any project requiring corrosion-resistant, lightweight M3 screws with a clean, low-profile head.

These screws are machined from high-strength, heat-treatable aluminum alloy and finished with an anodized coating. The anodized surface provides a hard, color-fast layer that resists corrosion, scratching, and oxidation.
Colors available are Royal Blue, Green, Golden, Dark Red, Black, Silver, Purple, Rose Red, and Sky Blue. Lengths available are M3 x 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 25mm, and 30mm. Select your preferred Color and Thread Diameter x Length combination from the variant options above.
These M3 button head screws use a hex socket (Allen key) drive. M3 button head screws typically require a 2mm hex key. We recommend confirming with a standard metric Allen key set before installation.
The anodized aluminum construction offers good corrosion and oxidation resistance, making these screws suitable for light outdoor use. For environments with constant salt spray or harsh chemicals, stainless steel fasteners are generally recommended instead.
The anodized finish is integrated into the surface of the aluminum rather than applied as a paint or coating, which means it is generally more resistant to fading and chipping than painted alternatives under normal use conditions.
These screws are manufactured to a tolerance of ±0.3mm, ensuring consistent dimensions and reliable thread engagement with standard M3 metric nuts and threaded inserts.
Yes, these M3 aluminum button head screws are compatible with standard M3 steel nuts and threaded inserts. Keep in mind that aluminum is softer than steel, so they are best suited for applications where load levels are within the alloy’s mechanical limits. Avoid over-torquing to prevent thread damage.
