The DIN 603 is a set of standards created by the Deutsches Institut für Normung (DIN), which specifies the dimensions, materials, and mechanical properties for carriage bolts. These standards ensure that carriage bolts, which are commonly used in woodworking and construction, meet specific quality and performance requirements. DIN 603 covers various aspects of carriage bolts, including their head shape, thread length, and shank diameter, to guarantee their suitability for different applications. By providing clear guidelines for the design and production of carriage bolts, the DIN 603 helps to ensure the safety and reliability of these fasteners in various structural and load-bearing applications.
