The DIN 931/ISO 4014 standard specifies the characteristics of hexagon head bolts with shank, thread from the head to the tip, and metric coarse pitch thread. These bolts are designed for use in structural steelwork and are primarily used for high-strength applications. The standard outlines the dimensions, mechanical properties, and tolerances for these bolts, ensuring consistency and reliability in their performance. DIN 931/ISO 4014 bolts are widely used in various industries where secure and durable fastening is essential, making them a crucial component in many engineering and construction projects.
