Purchasing din975 threaded rod Considerations

When purchasing DIN 975 threaded rods, in addition to price and minimum order quantity, consider the following: Material is key: Choose the material based on the intended use. Carbon steel is economical; stainless steel (especially 304 and 316) is corrosion-resistant and suitable for use in humid or corrosive environments; copper offers excellent conductivity; and aluminum is lightweight. Surface treatments affect durability: Commonly used include galvanizing (for rust prevention), passivation (for enhanced corrosion resistance of stainless steel), and Dacromet (for high strength and corrosion resistance). Choose the right material based on the intended use. Grade designations represent strength: for example, 4.8, 8.8, A307, etc. Higher numbers generally indicate higher strength. Certifications ensure quality: Look for certifications such as ISO9001 and ROHS, especially for export or high-standard industrial applications. Dimensions must be accurate: Confirm details such as thread size (e.g., M6, M8), length (1 meter, 3 meters), and whether the material is fully threaded.
