Aluminum Alloy Fastener

Aluminum alloy hexagonal hollow double-headed screws are lightweight and high-strength fasteners made of aluminum alloys (such as 6061-T6 or 7075), which have both corrosion resistance and low weight advantages. The two ends are taper threaded, which enhances the connection sealing and vibration resistance, and the inner holes at both ends are different in diameter, making it easy to adapt to different installation needs. The hexagon head design provides high torque load-bearing capacity, and the hollow structure can be weight-reduced and used for wiring or ventilation. Suitable for aviation, automotive and precision machinery fields, it is especially suitable for scenarios where lightweight, high strength and multifunctional integration is required. Custom size and surface treatment (such as anodizing).

Features:

Lightweight and high strength: Use aviation-grade aluminum alloys (such as 6061-T6, 7075), and the weight is more than 60% lighter than steel screws, while maintaining high strength and corrosion resistance.

Double-head taper thread design: The threads at both ends are tapered structures, which improve the tightness of the joint with the aluminum alloy matrix and prevent loosening. It is especially suitable for vibration environments (such as automobiles and drones).

Differentiated inner hole design: The diameters of the inner holes at both ends are different, and can be adapted to different pipelines (such as hydraulics, gas circuits) or weight reduction needs, and it is convenient for installation in multiple scenarios.

Hexagon head high torque bearing: The hexagon head design supports standard wrench operation, providing high torque tightening capability to avoid slip wires.

Hollow multifunctional structure: The hollow part can be integrated with wiring (cable/optical fiber), ventilation or weight loss, and is suitable for precision equipment (such as robots, aerospace components).

Product Application:

Aerospace and UAVs: used for lightweight connections such as aircraft skins, cabin structures, drone frames, etc., to reduce the overall weight.

New energy vehicles and electric vehicles: fixed battery pack, connected motor housing, and lightweight body structure.

Industrial robots and automation equipment: robotic arm joints, servo motor installation, high-precision transmission components.

High-end bicycles and motorcycles: Carbon fiber frame connection and suspension system tight.

Energy and power equipment: solar brackets, wind power equipment cabins, high-voltage electrical cabinets.

Medical and precision instruments: CT machines, surgical robots and other equipment that require a sterile environment.

Product Advantages:

The high strength ratio of aluminum alloys (such as 7075-T6) meets the aero load requirements, and the hollow structure can integrate cables or reduce weight.

Corrosion resistance (anodized treatment) adapts to humid environments, taper threads enhance shock resistance and prevent battery pack from loosening.

The hexagonal head is designed for high torque installation, and the hollow part can pass signal lines or cooling pipelines to reduce the complexity of external wiring.

Lightweight improves sports performance, and differentiated inner holes are adapted to hydraulic brake pipelines or sensor lines.

The weather resistance of aluminum alloy is better than that of ordinary steel, and the hollow structure can be used for ventilation and heat dissipation to reduce the impact of thermal expansion.

Surface anodization treatment is chemically resistant to chemical corrosion and has no magnetic interference to operate precision instruments.

FAQ

Q1: Why is it designed as a hollow structure? What is its practical use?

A1: Weight loss: 30%~50% lighter than solid screws, suitable for weight-sensitive applications (such as aviation, racing).

Q2: Why are the inner holes at both ends different in size?

A2: Adaptability: Large hole ends can run thicker pipelines (such as hydraulic pipes), and small hole ends are used for fine lines (such as sensor signal lines)

Q3: What are the advantages of taper thread?

A3: Anti-loosening and earthquake resistance: The taper thread is closer to the base body, suitable for high vibration environments (such as engines, wind power equipment)
