DIN934 /hexagon nut
DIN934 can be classified according to the following materials:
1. Carbon steel: Such as C10 or C15 carbon steel, etc., are often used in general mechanical connection and fastening applications. There are also heat-treated carbon steel materials like grade 8.8 carbon steel, which can meet higher strength requirements.
2. Stainless steel: Usually A2 – 70 (equivalent to 304 stainless steel), it has good corrosion resistance and oxidation resistance, and is suitable for environments with high requirements for corrosion resistance, such as the chemical industry, food industry, medical device industry, etc.
3. Aluminum alloy: Such as ALMg4.5Mn or ALMg5, etc., has the characteristics of light weight and corrosion resistance, and is often used in fields with requirements for weight, such as aerospace and automotive manufacturing.
DIN934 is a nut standard, and the nuts under this standard can be classified into various types such as carbon steel, stainless steel, and aluminum alloy according to the materials, so as to be suitable for different mechanical connections and environmental requirements.https://pangjinfasteners.com/about-us.html

DIN934 is a nut standard, and the nuts under this standard can be classified into various types such as carbon steel, stainless steel, and aluminum alloy according to the materials, so as to be suitable for different mechanical connections and environmental requirements.
The common surface treatments of fasteners conforming to the DIN934 standard are as follows:
1. Smooth surface treatment: That is, no additional surface treatment is carried out, and the original color of the metal is maintained. It is often used in occasions where the requirements for appearance and anti-corrosion are not high.
2. Zinc plating: It includes electro-galvanizing and hot-dip galvanizing. The electro-galvanized layer is thin and has a beautiful appearance; the hot-dip galvanized layer is thick and has good anti-corrosion performance, which is suitable for harsh environments such as the outdoors.
3. Nickel plating: It can improve the corrosion resistance and wear resistance of the fasteners, and at the same time endow them with a good appearance. It is often used in occasions with high decorative requirements or where a certain electromagnetic shielding performance is required.
4. Blackening treatment: Also known as boiling black. Through chemical treatment, a black oxide film is formed on the surface of the fasteners, which can improve the anti-corrosion performance to a certain extent, and the cost is relatively low.
5. Dacromet treatment: It is a zinc-chromium coating treatment technology, which has excellent characteristics such as corrosion resistance, high-temperature resistance and no hydrogen embrittlement, and is suitable for high-strength fasteners.
6. Phosphating treatment: A phosphate chemical conversion film is formed on the surface of the fasteners, which can improve the corrosion resistance, lubricity and paint adhesion, etc.
The above content is for reference only. In practical applications, different surface treatment methods may be selected according to specific requirements and environments.
1. About package
1.1 In our daily production operations, we always maintain a rigorous and scientific attitude towards the product packaging process. When it comes to selecting materials for the inner packaging of products, we typically use plastic films, plastic bags, or plastic trays. Thanks to their excellent sealing properties and corrosion resistance, these materials can effectively protect products and perform the functions of moisture prevention and rust prevention remarkably well. Especially for those fastener products with high manufacturing precision or those that are relatively fragile and vulnerable, we will additionally use cushioning materials with excellent shock absorption performance, such as foam plastics and sponges, to further enhance the protection. In this way, we can avoid product damage caused by various collisions and jolts during transportation, ensuring the integrity and quality of products to the greatest extent. Regarding the outer packaging, we usually choose corrugated cardboard boxes, wooden cases, or plywood cases. Corrugated cardboard boxes are lightweight and cost-effective, making them suitable for fasteners with relatively light weights. Wooden cases and plywood cases have high strength, which not only allows them to bear heavier loads but also enables them to meet the fumigation requirements for export packaging, making them ideal for heavy-duty or vulnerable fasteners.
1.2 In addition, we attach great importance to the personalized needs of each customer and are committed to providing customized packaging services. If customers have unique design requirements for the color, pattern, and size of the packaging, or if they expect to print exclusive brand logos on the packaging to enhance their brand image, we will go all out, mobilize various resources of the company, and make every effort to meet each special requirement of the customers. We strive to create unique packaging solutions for customers that are in line with their brand concepts and market positioning.
2.About payment
Our company uniformly adopts T/T (Telegraphic Transfer) as the payment method. For regular orders, a 30% advance payment is required at the time of placing the order to initiate the order process. The remaining 70% balance must be fully settled before the goods are loaded onto the vehicle to ensure a seamless connection between the payment transfer and the goods transportation process.
In the case of customized products, considering the particularity of their production, the advance payment proportion is adjusted to 30% - 50%, which needs to be paid upon finalizing the customized details and signing the contract. The remaining balance is also required to be paid off before the goods are loaded. Only when the balance is cleared can the goods be guaranteed to be delivered to your designated location on time and smoothly, avoiding any possible delays or disputes.
3.About Delivery & shipment
For in-stock products, with the support of our efficient logistics distribution system and internal coordination mechanism, we promise to complete the delivery within 10 days, enabling you to obtain the desired goods promptly. As for customized products, since they need to be produced according to specific specifications and requirements, involving multiple processes such as design confirmation, raw material procurement, and production, we will generally complete the delivery within one month, ensuring that you can receive the customized products that meet your needs as scheduled.
