Auto Parts Nut

Product Description:

The aluminum alloy flange hex nuts are made of high-strength aluminum alloys such as 6061-T6/7075, featuring both lightweight and corrosion resistance. The hex flange design provides a larger contact area, enhancing anti-loosening performance and is suitable for vibration environments such as automobiles and aviation. The surface is treated with anodizing, offering strong weather resistance, electrical insulation, and non-magnetism, and complies with ISO/DIN standards. The flange integrates a gasket function, simplifying installation and improving sealing performance. It is widely used in lightweight structures such as new energy battery boxes and photovoltaic brackets. Customization is available for non-standard specifications (hole diameter, flange diameter), and it is compatible with M6-M24 bolts.

Product Features:

Lightweight and high-strength design: Made of 6061-T6/7075 aluminum alloy, with tensile strength ≥ 310 MPa (up to 560 MPa for 7075), and weighing only 1/3 of steel nuts. It is suitable for weight-sensitive fields such as new energy vehicles and aviation, reducing the overall structural load.

Flange anti-loosening function: The flange diameter is 30%-50% larger than that of standard hex nuts, distributing pressure and reducing the risk of substrate deformation. Anti-loosening teeth are optional: The flange bottom can be processed with sawtooth patterns or nylon inserts, improving anti-loosening performance by 60% in vibration environments.

Outstanding corrosion resistance: Hard anodizing (HV ≥ 800) or electrophoretic coating, passing the 500-hour salt spray test (ASTM B117).

Non-magnetic and insulating: Suitable for anti-interference scenarios such as medical equipment and precision instruments.

Convenient installation: Compatible with wrenches, standard hex heads (ISO 4032) are suitable for common tools, and the flange provides visual alignment references.

Pre-assembly design: Can be pre-assembled with bolts into a combined part, reducing on-site assembly time.

Product Applications:

New Energy Vehicles: Battery box fixation, motor housing connection, lightweight vehicle body structure

Photovoltaic New Energy: Solar bracket assembly, inverter box fastening, tracking system rotating joint

Aerospace: Unmanned aerial vehicle body structure connection, satellite equipment bracket fixation, cabin interior parts installation

High-end Medical Equipment: CT/MRI equipment assembly, surgical robot joint, mobile medical vehicle body

Rail Transit: High-speed rail cabin interior fixation, metro pantograph bracket, track signal equipment box

Intelligent Equipment Manufacturing: Industrial robot arm joint, AGV cart structural parts, 3D printing equipment frame

Shipbuilding and Marine Engineering: Marine aluminum alloy deck fixation, seawater desalination equipment, deep-sea detector shell

Product Advantages:

Ultra-light Material: Utilizing aerospace-grade 6061-T6/7075 aluminum alloy, with a density of only 2.7g/cm³ (35% of steel). A typical M12 nut weighs only 8.2g (22g for a steel nut of the same specification). Using it throughout a new energy vehicle can reduce weight by 4-6kg.

Structural Optimization: Patented flange plate hollow design, reducing weight by 15% while maintaining strength. The through-hole version can integrate cables, reducing additional wiring space.

FAQ

Q1: How to choose between 6061-T6 and 7075-T6?

A1: 6061-T6: General-purpose (tensile strength 310MPa), low cost, suitable for general industrial applications. 7075-T6: Aviation grade (tensile strength 560MPa), 30% higher in price, used for critical load-bearing parts.

Q2: Is it conductive? What is the resistance value?

A2: After standard anodizing treatment, it is insulated (surface resistance > 10¹²Ω). For conductivity, special treatment is available: local deoxidation (contact resistance < 0.5Ω).

Q3: Will the anti-loosening teeth damage the contact surface?

A3: The sawtooth angle is optimized (60° helical teeth). For aluminum alloy base: indentation depth ≤ 0.05mm (reversible deformation). For carbon fiber plates: it is recommended to add a stainless steel washer (to prevent crushing). A non-destructive anti-loosening solution (non-metallic friction washer) is provided.
