DIN 975 standard specifies the properties of metric threads that are threaded rods with coarse pitch thread and fine pitch thread made of steel. These threaded rods are commonly used in construction and industrial applications for fastening, joining, and securing components. The standard covers the dimensions, materials, mechanical properties, and tolerances for metric threaded rods to ensure their compatibility and interchangeability with other components and fasteners. Additionally, DIN 975 provides guidance on the marking of threaded rods to indicate their compliance with the standard and facilitate proper identification during installation and inspection. This standard plays a crucial role in promoting safety, reliability, and uniformity in the use of metric threaded rods across various industries.
