This comprehensive guide explores the China DIN 125 standard, detailing its specifications, applications, and significance in the manufacturing and engineering sectors. We’ll delve into its key characteristics, comparing it to other relevant standards, and offering practical insights for those working with fasteners adhering to this specification. Learn how to identify, select, and utilize China DIN 125 compliant components effectively.
DIN 125 is a German industrial standard (Deutsche Industrie Norm) specifying dimensions and properties for hexagonal head screws with a coarse thread. While originating in Germany, its influence extends globally, including China, where its adoption is significant. The China DIN 125 standard essentially mirrors the original German DIN 125, detailing specific parameters for these fasteners, ensuring interchangeability and consistent quality.
China DIN 125 screws are distinguished by their hexagonal head shape, coarse thread pitch, and precise dimensional tolerances. These characteristics contribute to their strength, reliability, and suitability for a wide range of applications. The standard covers various screw sizes, materials, and surface treatments, offering flexibility in design and selection.
China DIN 125 screws are typically manufactured from various materials, including carbon steel, stainless steel, and alloy steel. The choice of material depends on the intended application and the required strength and corrosion resistance. Stainless steel variants offer superior corrosion resistance, making them ideal for outdoor or corrosive environments.
The standard specifies a coarse thread profile for optimal strength and ease of installation. Precise dimensions are outlined for each screw size, ensuring compatibility and proper engagement with matching nuts and components. The China DIN 125 standard details these dimensions clearly to maintain uniformity.
A range of surface treatments are often applied to China DIN 125 screws to enhance their performance and longevity. These include zinc plating, galvanizing, and other coatings, protecting against corrosion and improving wear resistance. The specific treatment selected depends on the environmental conditions and the application requirements.
While similar to other international standards for hexagonal head screws, China DIN 125 may have subtle differences in tolerances or material specifications. Understanding these nuances is crucial for ensuring compatibility and avoiding potential issues during assembly and operation.
| Standard | Material | Thread Type | Applications |
|---|---|---|---|
| China DIN 125 | Carbon Steel, Stainless Steel | Coarse | General fastening |
