DIN 912 Hexagon Socket Head Screws: A Comprehensive GuideDIN 912 hexagon socket head screws are a common type of fastening element used in a wide range of applications. This article provides a comprehensive overview of DIN 912 screws, covering their specifications, materials, applications, and advantages. We'll also explore how to select the right DIN 912 screw for your specific needs.
The DIN 912 standard, established by the Deutsches Institut für Normung (DIN), specifies the dimensions and tolerances for hexagon socket head screws. Key specifications include:
These screws feature a hexagon socket head, designed to be driven by a hexagon key (Allen wrench). The head's size and shape are precisely defined in the standard to ensure proper fit and torque.
The DIN 912 standard specifies the thread profile, pitch, and tolerance. Common thread types include metric coarse (M) and metric fine (mf) threads. The choice of thread depends on the application and required strength.
DIN 912 screws are available in a wide range of lengths, from a few millimeters to several centimeters. The length is crucial for ensuring proper engagement with the mating material.
DIN 912 screws are typically made from various materials, including steel (often with different grades and surface treatments), stainless steel, and brass. Material selection depends on the application's requirements for strength, corrosion resistance, and temperature tolerance.
The choice of material significantly impacts the performance of a DIN 912 screw. Common materials include:
| Material | Properties | Applications |
|---|---|---|
| Steel (Various Grades) | High strength, good machinability | General purpose applications |
| Stainless Steel (e.g., A2, A4) | Excellent corrosion resistance | Outdoor applications, corrosive environments |
| Brass | Good corrosion resistance, non-magnetic | Applications requiring corrosion resistance and non-magnetism |
Surface treatments such as zinc plating, galvanizing, or passivation can further enhance corrosion resistance and extend the lifespan of the screws. For specific requirements, consult the Hebei Dewell Metal Products Co., LTD for a wide selection of high-quality DIN 912 screws.
