Aluminum Nuts Bolts And Washers
Weight Range ： 0.5g–500kg
Dimensional tolerance ： ±0.1mm
Aluminum nuts bolts and washers are the fasteners of choice for lightweight designs. Its density is approximately 2.7 grams per cubic centimeter. Compared with steel, it can reduce weight by about 65%. At the same time, this type of fastener has reliable mechanical properties. For example, the tensile strength of 6061-T6 aluminum alloy can exceed 310 MPa.
Aluminum fasteners also excel when it comes to durability. After hard anodizing treatment, a dense oxide layer of more than 15 microns can be formed on the surface. This allows it to pass more than 500 hours of neutral salt spray testing and has excellent corrosion resistance. In addition, aluminum is nearly 100% recyclable, which greatly increases the environmental protection value of the product throughout its life cycle. It provides a solid and reliable connection solution for all types of sustainable manufacturing projects.

Benefits
Extremely lightweight
The density of aluminum is only about 2.7 g/cm³. About one-third that of steel. Under the same volume, aluminum fasteners can reduce weight by about 65%.
This is critical in areas such as aerospace and racing. It can directly improve energy efficiency and load.
High specific strength
For example, 6061-T6 aluminum alloy has a tensile strength of more than 310 MPa. But its density is very low. Therefore, the specific strength is very outstanding.
It can meet both structural strength and weight requirements. Ideal for applications such as aircraft and robots.
Good electrical conductivity
Aluminum is a good conductor. The electrical conductivity is approximately 60% of pure copper. The weight is much lighter.
Therefore it is suitable for occasions requiring electrical connections. Its good thermal conductivity can also help dissipate heat and improve safety.
Easy to process
Aluminum alloy is easy to perform precision processing such as turning and milling. Fasteners with complex shapes can be manufactured.
The surface oxide film provides protection and reduces maintenance. High-quality aluminum fastening systems have a lifespan of more than 30 years. Significantly reduces the whole life cycle cost.
why choose us
-
Weight loss and efficiency gain
The density is only about 35% of steel. After replacement, it can significantly reduce the weight of the system and directly improve the energy efficiency and speed of the vehicle. It is the first choice for lightweight design.
-
Corrosion resistance and long life
After the surface is hard anodized, the salt spray resistance can reach more than 500 hours. It is suitable for harsh environments such as moisture, acid and alkali, and has a long maintenance cycle.
-
Good electrical and thermal conductivity
The electrical conductivity is about 60% of pure copper and it is lighter in weight. It is often used in key parts that require electrical connection or heat dissipation, such as power cabinets and electronic equipment.

F A Q
Is the size standard based on American standards or European standards?
- We have both metric (ISO/DIN) and American (UNC/UNF) threads. You send us drawings or samples and we can match them. The tolerance can be controlled within 0.1 mm.
What is the minimum order quantity? Can they be mixed?
- The MOQ for standard parts is 1,000 sets. Nuts, bolts, and washers can be mixed in the same order, and we provide complete packages to facilitate your installation.
How long does the delivery take? How to ship?
- Regular models are in stock and will be shipped within 3 days of placing the order. Customized parts take 15-20 days. We often use DHL/UPS for air freight, and we also support sea freight LCL, and will help you prepare compliant customs clearance documents.
Can you provide material reports and test certificates?
- Of course. Each shipment comes with a material report (MTC). Salt spray test reports and dimensional inspection reports can also be provided upon request to ensure compliance with your quality system requirements.
What are the payment methods?
- T/T and letter of credit are supported, and small-amount trial orders via PayPal or credit card are also accepted. 30% deposit, 70% paid upon receipt of copy of bill of lading, long-term customers have more flexible arrangements.
