This guide provides a comprehensive overview of DIN 912 screws, helping you understand their specifications, applications, and where to buy high-quality options. We'll cover key features, material choices, and considerations for selecting the right screw for your project. Learn how to identify genuine DIN 912 screws and ensure you're making the best purchasing decision.
DIN 912 screws, also known as hexagon socket head cap screws, are a common type of fastening element specified by the German standard DIN 912. These screws are characterized by their hexagonal socket head, which allows for tightening with a hexagon key (Allen wrench). This design provides a clean, flush finish and excellent torque transmission. The DIN912 standard ensures consistency in dimensions and quality, making them reliable for various applications.
DIN 912 screws are available in various materials and grades, each offering different properties and suitability for specific applications. The most common materials include:
The choice of material depends heavily on the intended application and environmental conditions. For high-strength applications, higher-grade steel screws are preferred. If corrosion resistance is paramount, stainless steel is the better option. Consult the relevant specifications and engineering standards for your specific project needs.
Sourcing high-quality DIN912 screws is crucial for ensuring project success. Reputable suppliers will offer certifications and guarantees of conformity to the DIN 912 standard. Consider these factors when choosing a supplier:
For high-quality DIN 912 screws, consider exploring reputable suppliers like Hebei Dewell Metal Products Co., LTD. They offer a wide range of fasteners meeting stringent quality standards.
DIN 912 screws are versatile and used across various industries and applications, including:
| Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Applications |
|---|---|---|---|
| 4.6 | 240 | 130 | General purpose, low-stress applications |
| 8.8 | 800 | 640 | Medium to high-stress applications |
| 10.9 | 1000 | 830 | High-strength applications, demanding environments |
Note: Tensile and yield strength values are approximate and may vary slightly depending on the manufacturer and specific material properties. Consult the manufacturer's data sheet for precise values.
This guide provides a comprehensive starting point for understanding and purchasing DIN 912 screws. Remember to always consult relevant standards and the manufacturer's specifications to ensure you select the appropriate screw for your specific application.
