Standard steel hex nuts 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 anodized aluminum hex full nuts give you a secure, corrosion-resistant fastening solution that keeps your build lightweight and visually sharp.
Machined from high-strength, heat-treatable aluminum alloy and finished with a durable anodized coating, each nut features a standard hexagonal profile for easy wrench or socket installation. Available in M3, M4, M5, and M6 thread diameters and 11 anodized colors — Rose Red, Silver, Orange, Purple, Dark Red, Sky Blue, Black, Royal Blue, Titanium Gray, Golden, and Green — manufactured to a ±0.3mm tolerance.
These hex nuts 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 weight savings, corrosion resistance, and color coordination are priorities.
Ideal for high-end aluminum alloy bicycle frame assembly where lightweight fastener hardware and visual appeal are equally important.
The lightweight aluminum construction makes these hex nuts a natural fit for RC aircraft, drone frames, and aerospace model toy accessories where minimizing weight is critical.
Add a pop of color to custom computer cases, cooling systems, and electronics enclosures with anodized nuts that complement your build’s color scheme.
Suitable for golf equipment, mold processing, mechanical equipment assembly, and any project requiring corrosion-resistant, lightweight hex fasteners with a clean finish.

These hex nuts 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.
Thread sizes available are M3, M4, M5, and M6. Colors available are Rose Red, Silver, Orange, Purple, Dark Red, Sky Blue, Black, Royal Blue, Titanium Gray, Golden, and Green. Select your preferred Color and Size (Thread Diameter) combination from the variant options above.
These are standard metric hex nuts and fit standard metric wrenches or sockets. The wrench size required depends on the thread diameter: M3 typically uses a 5.5mm wrench, M4 uses 7mm, M5 uses 8mm, and M6 uses 10mm. We recommend confirming with a standard metric wrench set before installation.
The anodized aluminum construction offers good corrosion and oxidation resistance, making these nuts suitable for light outdoor use and general automotive applications. 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 hex nuts are manufactured to a tolerance of ±0.3mm, ensuring consistent dimensions and reliable thread engagement with standard M3–M6 metric bolts and screws.
Yes, these M3–M6 aluminum hex nuts are compatible with standard metric steel bolts and screws. 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.
