Products Description
The DIN547 Drilled Holes in One Face Round Nut is a specialized fastening component designed to provide a secure and stable connection in applications that require a drilled hole for pinning, locking, or additional fastening features. These round nuts are manufactured according to the DIN547 standard and are typically used in mechanical and industrial applications where the added drilled hole enables additional functionalities like securing with a cotter pin, safety pin, or wire.
These round nuts are particularly useful when it is critical to prevent loosening due to vibration or rotational forces. The drilled hole on one face allows for easy integration with a locking mechanism, making them ideal for securing machinery parts, bolts, and fasteners in high-stress environments.

Products Process
The production of DIN547 Drilled Holes in One Face Round Nuts involves several precise steps to ensure high quality, durability, and compliance with the DIN standard:
Material Selection: The first step in the manufacturing process is selecting high-quality materials, such as carbon steel, stainless steel, or alloy steel. Materials are chosen based on the application's strength, corrosion resistance, and durability requirements.
Forging or Machining: The round nuts are formed either through cold forging or machining from solid stock, depending on the material and size. Forging ensures better material strength, while machining provides higher precision for the drilled hole and overall dimensions.
Drilling of Holes: After the nut has been formed, a precision drilling operation is performed to create a hole in one of the faces of the nut. The hole is typically used for a pin, wire, or cotter pin to lock the nut into place and prevent loosening.
Heat Treatment: To enhance the mechanical properties of the nut, heat treatment is often applied. This process improves the nut's hardness and tensile strength, ensuring it can withstand heavy loads and vibrations.
Surface Treatment: Depending on the application and environment, the nuts may undergo various surface treatments such as galvanizing, passivation, black oxide coating, or simply a plain finish. These treatments improve corrosion resistance and provide aesthetic benefits.
Quality Control: Each nut undergoes rigorous quality checks. This includes dimensional inspections, thread integrity checks, and material testing to ensure they meet the required DIN547 standards and function as expected under stress.
Products Application
Machinery & Equipment: Used in mechanical systems to secure parts and prevent loosening due to vibrations. Ideal for rotating machinery, conveyor systems, and heavy-duty industrial equipment.
Automotive & Aerospace: Essential in automotive or aerospace applications where vibration and dynamic forces could otherwise loosen a regular nut.
Agricultural Equipment: Suitable for farming and agricultural machinery that operates in tough environments with high vibrations.
Construction Industry: Used for securing bolts and fasteners in heavy-duty construction and infrastructure projects.
Locking Mechanisms: Perfect for applications requiring an additional locking mechanism, such as pinning, safety wires, or other locking methods.
FAQ
Q: What materials are available for the DIN547 Drilled Holes in One Face Round Nuts?
A: These nuts can be made from carbon steel, stainless steel, or alloy steel. The material choice depends on the application, with stainless steel being preferred for corrosion resistance and alloy steel for high-strength requirements.
Q: What is the purpose of the drilled hole in the nut?
A: The drilled hole in one face of the nut is designed to allow for the insertion of a pin, cotter pin, or safety wire. This locking mechanism helps prevent the nut from loosening due to vibrations or mechanical stress.
Q: What sizes are available for the DIN547 round nuts?
A: The DIN547 round nuts are available in sizes ranging from M4 to M64. We can also produce custom sizes based on specific customer requirements.
Q: Can these nuts be used in outdoor or corrosive environments? A: Yes, the nuts are available with various surface treatments such as zinc plating, passivation, and black oxide to protect against corrosion. Stainless steel versions also offer excellent resistance to rust and corrosion.
Q: Are these round nuts suitable for high-temperature applications?
A: Yes, these round nuts can withstand temperatures ranging from -40°C to 150°C. For higher temperatures, special materials and coatings can be provided upon request to ensure reliable performance in extreme environments.
Q: How does the drilled hole improve the nut's performance?
A: The drilled hole allows for additional locking mechanisms such as cotter pins or safety wire, which prevent the nut from loosening over time. This is particularly important in high-vibration environments, ensuring the nut stays securely in place.
Q: Can I reuse a DIN547 round nut if it has been previously locked with a pin?
A: Yes, DIN547 round nuts can be reused if the threads and hole are in good condition. However, the locking pin or safety wire may need to be replaced if it shows signs of wear or damage.
Q: What finishes are available for the DIN547 round nuts?
A: We offer a variety of finishes including zinc plating, passivation, black oxide, and plain finishes. Custom finishes are available to suit your specific environmental and aesthetic needs.
Q: Can I order custom-sized or custom-drilled DIN547 round nuts?
A: Yes, we can provide custom sizes and drilling specifications. Please contact us with your specific requirements, and we will tailor the product to meet your needs.
