Malaxy Cube Nut, also known as a six-sided square nut, threaded cube connector, or square block nut, is a precision-machined cubic fastener featuring six faces that are all perfect squares of equal dimensions, with a centrally located threaded through-hole. Unlike traditional square nuts (DIN 557/562) which are thin and flat, our cube nuts have equal height, width, and depth, creating a true cubic geometry that offers superior load distribution, aesthetic symmetry, and multi-axis installation flexibility.

These cube-shaped nuts are designed for applications requiring precise alignment, clean aesthetics, and reliable threaded connections. Manufactured to exacting tolerances, Malaxy Cube Nuts serve as both functional fasteners and structural connectors in furniture assembly, display fixtures, machinery frames, 3D printers, robotics, and industrial equipment.

Key Features & Technical Specifications

• True Cubic Geometry: All six faces are perfect squares of equal dimensions, with height equal to width equal to depth. This unique shape provides balanced load distribution and allows installation from any of the six faces.

• Centered Threaded Hole: Precision-tapped thread runs through the exact center of the cube, perpendicular to two opposing faces. Available in metric coarse threads (standard) and fine threads upon request.

• High-Precision CNC Machining: Manufactured using advanced CNC machining processes for consistent dimensional accuracy, clean surface finish, and tight tolerance control. Thread precision meets ISO 6H standards.

• Multiple Material Options:

  • Aluminum Alloy (6061 / 6063 / 7075): Lightweight, corrosion-resistant, and easy to machine. Ideal for applications where weight reduction is critical, such as drones, robotics, and portable equipment. 7075 grade offers higher strength for demanding applications.

  • Carbon Steel (Grade 8.8 / 10.9 / 12.9): High tensile strength for heavy-duty structural and industrial applications. Grade 12.9 provides maximum strength for critical load-bearing connections.

  • Stainless Steel 304 (A2): Excellent corrosion resistance for indoor and general-purpose applications including food processing equipment and architectural hardware.

  • Stainless Steel 316 (A4): Superior corrosion resistance for marine environments, chemical processing, and outdoor applications with exposure to saltwater or harsh chemicals.

• Thread Sizes Available: Metric M3, M4, M5, M6, M8, M10, M12, M16, M20. Custom thread sizes available for OEM orders.

• External Dimensions: Standard cube side lengths correspond to thread size (e.g., M6 = 12mm cube). Custom dimensions available upon request—any cube size can be paired with any thread size to meet specific design requirements.

• Surface Finishes:

  • Anodizing (Aluminum): Clear, black, or custom colors for enhanced corrosion resistance and aesthetic appeal

  • Zinc Plating (Carbon Steel): Blue, white, or yellow passivation for economical corrosion protection

  • Black Oxide (Carbon Steel): Matte black finish for mild corrosion resistance and non-reflective appearance

  • Plain Finish: As-machined surface for further processing or cost-sensitive applications

  • Passivation (Stainless Steel): Removes surface contaminants and restores corrosion resistance

• Additional Features:

  • Available with threaded blind holes (one open end only) upon request

  • Multiple threaded holes on different faces available for custom configurations

  • Countersunk holes available for flush-mount screw applications

Applications

• Furniture Assembly: Modular furniture connectors, shelving systems, display stands, exhibition booths, and ready-to-assemble (RTA) furniture. The cubic shape provides a clean, professional appearance for visible connections.

• 3D Printers & CNC Machines: Frame connectors, gantry supports, and structural joints where precise alignment is critical. Cube nuts serve as corner connectors for aluminum extrusion profiles.

• Robotics & Automation: Robot arm joints, mounting blocks, sensor brackets, and end-effector connections. The multiple square faces provide 90° mounting interfaces.

• Industrial Machinery: Equipment frames, guard mounting, enclosure assembly, and structural connections requiring high strength and stability.

• Display & Retail Fixtures: Point-of-purchase displays, trade show booths, retail shelving, and signage mounting. Anodized aluminum cube nuts offer both function and visual appeal.

• DIY & Maker Projects: Custom furniture, workbenches, tool stands, and hobbyist projects. The simple geometry and multiple material options make cube nuts popular in maker communities.

• Aerospace & Drone Applications: Lightweight aluminum cube nuts for airframe connections and component mounting where weight reduction is critical.
