DIN 125 weights refer to a specific classification of flat washers that conform to the German Institute for Standardization (Deutsches Institut für Normung) standards. These washers are designed to distribute the load of a threaded fastener, such as a bolt or screw, over a larger surface area, thereby reducing the risk of damage to the material being fastened. The DIN 125 standard specifies various dimensions, including inner and outer diameters as well as thickness, ensuring compatibility and reliability in mechanical applications. These weights are commonly utilized in a wide range of industries, including construction, automotive, and manufacturing, where secure fastening is critical for structural integrity and performance. The use of DIN 125 weights enhances the durability and effectiveness of fastening systems, making them an essential component in engineering and assembly processes.
