Buy DIN 934 M20: A Comprehensive Guide
This guide provides a comprehensive overview of purchasing DIN 934 M20 hex head screws, covering specifications, applications, sourcing, and quality considerations. Learn where to find reliable suppliers and ensure you select the right screws for your project.
Understanding DIN 934 M20 Hex Head Screws
What is a DIN 934 M20 Screw?
The DIN 934 standard specifies a type of hexagon head bolt, and the M20 refers to its nominal diameter of 20 millimeters. These DIN 934 M20 screws are commonly used in various engineering and construction applications due to their strength and reliability. They are characterized by their fully threaded shaft and a precisely manufactured hexagon head, allowing for secure tightening with a wrench.
Key Specifications of DIN 934 M20
Key specifications to consider when buying DIN 934 M20 screws include:
- Material: Common materials include steel (often with various coatings like zinc plating for corrosion resistance), stainless steel (for higher corrosion resistance), and other specialized alloys depending on the application.
- Thread Pitch: The thread pitch determines the spacing between threads. Knowing the correct thread pitch is crucial for proper engagement and strength.
- Length: The overall length of the screw, including the head, is critical for ensuring sufficient grip and penetration.
- Class (Property Class): This indicates the screw's tensile strength. Higher classes denote greater strength. For example, a 8.8 class screw is stronger than a 4.6 class.
- Surface Finish: The surface finish can impact corrosion resistance and aesthetic appeal.
Applications of DIN 934 M20 Screws
DIN 934 M20 screws find applications in a wide range of industries, including:
- Heavy machinery manufacturing
- Construction and infrastructure projects
- Automotive industry
- General engineering and fabrication
