Product Introduction
The aluminum alloy hexagonal double-ended screws are manufactured from high-strength aluminum alloys (such as 6061-T6/7075). The conical screw design enhances the thread grip force and shock resistance. The hexagonal head structure at both ends facilitates bidirectional installation. The middle through-hole reduces the weight by over 30% and can integrate wiring or ventilation functions. The surface is treated with anodizing, which is corrosion-resistant and insulating. It is suitable for lightweight applications in aviation and new energy vehicles. It complies with ISO/DIN standards and supports non-standard customized conical ratios (1:10/1:16) and hole diameter sizes.
Product features
1. Tapered thread design: The screw adopts a 1:10 or 1:16 taper, enhancing the tightness of the thread engagement, preventing loosening and vibration, and is particularly suitable for high-vibration environments (such as new energy vehicles, drones).
2. Hollow weight reduction structure: The design with an intermediate through hole reduces weight by 30%-50%, and can integrate cable routing or gas/liquid channels, improving the functional integration.
3. Bidirectional hexagonal head installation: Both ends have hexagonal heads that support two-way wrench operation, making installation flexible and suitable for narrow spaces or scenarios requiring bilateral tightening.
4. High-strength lightweight: Using 6061-T6/7075 aluminum alloy, with tensile strength ≥ 300 MPa, the weight is only 1/3 of that of steel screws, suitable for fields that are sensitive to weight (such as aerospace).
5. Adaptable to harsh environments: Working temperature range: -50℃ to 150℃. **Passes salt spray test for ≥ 500 hours (316 stainless steel bushings are optional, further enhancing corrosion resistance).
Product Application
1. New energy vehicles and electric vehicles: Application of battery packs fixation, motor housing connection, lightweight body structure
2. Aerospace and unmanned aircraft: Application of aircraft skins, wing structures, unmanned aircraft frame assembly
3. Industrial robots and automation equipment: Application of mechanical arm joints, servo motor installation, precision transmission components
4. High-end bicycles and motorcycles: Application of carbon fiber frame connection, suspension system tightening
5. Energy and power equipment: Application of solar support structures, wind power equipment, high-voltage electrical cabinets
6. Medical and precision instruments: Application of CT machines, surgical robots, laboratory equipment
7. Ships and marine engineering: Application of lightweight ship body structures, deck equipment fixation
Product advantages
1. Material Advantage: Lightweight design significantly reduces structural weight.
2. Hollow Structure: The design with an internal through-hole further reduces weight (weight reduction of 30%-50%), and can integrate cables or fluid channels, optimizing space utilization.
3. Anti-loosening and Anti-vibration: 1:10 or 1:16 taper threads provide progressive engagement, dispersing stress distribution. The first three-threaded screws can bear over 70% of the load, significantly reducing the risk of loosening in vibration environments.
4. Improved Sealing: The taper fit can form a metal seal, suitable for low-pressure gas/liquid systems (such as battery cooling pipelines).
5. Bidirectional Operation: The six-sided head at both ends supports double-sided wrench tightening, suitable for narrow spaces or blind assembly scenarios (such as robot joints).
6. High Torque Capacity: The hexagonal head is cold forged strengthened, with an anti-torsion strength of ≥8.8 grade, avoiding the risk of slip.
7. Cable Management: The through-hole can accommodate sensor wires, optical fibers, etc., reducing external wiring clutter (such as drone frames).
8. Cost Optimization: Aluminum alloy material reduces transportation and installation costs, and the hollow structure reduces material usage.
9. Standard Certification: Compliant with international standards such as ISO 14583 and DIN 7337, supporting RoHS/REACH environmental requirements.
FAQ
Q1: What is the material of the aluminum alloy hexagonal double-ended screw? How is its corrosion resistance?
A1: Commonly used are 6061-T6 (general type) and 7075-T6 (high-strength) aluminum alloys. Their tensile strengths reach 310 MPa and 560 MPa respectively.
Q2: What are the advantages of conical threads? How to choose the conical ratio?
A2: Anti-loosening: The risk of loosening in vibration environments is reduced by more than 60%.
Sealing: It can be used in low-pressure fluid systems without additional sealing rings.
Q3: Does the diameter of the hollow through-hole affect the strength? What is the maximum hole diameter limit?
A3: Strength impact: When the hole diameter is ≤ 1/3 of the screw diameter, the strength loss is <10% (verified by FEA).
Maximum hole diameter: The standard product supports Φ2mm - Φ12mm (M6 - M20 specifications), and non-standard can be customized to Φ20mm (requires strength verification).
Q4: Is the hexagonal double-ended design prone to thread breakage? How to install it correctly?
A4: Anti-slip design: The hexagonal head is strengthened by cold forging, with hardness ≥ 80 HRB, and it is accompanied by a dedicated installation sleeve (to prevent rotation damage).
Installation suggestion: Use a torque wrench
