DIN 975, also known as a threaded rod, is a standard set by the Deutsches Institut für Normung (DIN) for the manufacturing of externally threaded rods commonly used in construction, plumbing, and mechanical applications. This standard dictates the dimensions, materials, and tolerances of threaded rods to ensure uniformity and compatibility across various industries. Manufacturers and suppliers adhere to DIN 975 specifications to guarantee the quality and performance of threaded rods in different engineering and construction projects. With its detailed requirements and guidelines, DIN 975 plays a crucial role in facilitating the production and use of threaded rods in a wide range of applications.
