DIN 975 refers to a standardized specification originating from the German Institute for Standardization (Deutsches Institut für Normung), which delineates the characteristics of fully threaded rods, also known as threaded bars. This specification outlines various key attributes such as dimensions, tolerance, strength, and material composition. The rods covered under DIN 975 are elongated, with continuous external threading along their entire length, serving a wide array of applications across engineering, construction, and manufacturing sectors. These threaded rods are utilized for assembling, securing, or suspending components, and are available in a variety of materials including steel, stainless steel, and non-ferrous metals, each selected based on the environmental conditions and mechanical requirements of the application. The standard ensures compatibility and interoperability, facilitating international trade and ensuring quality and reliability in the use of threaded rods.
