DIN 912 defines cylindrical head bolts with an internal hex socket (Allen). These bolts are used in applications that require high tightening torque and precise assembly. The Allen socket design allows easy tightening with standard hex keys and provides installation in confined spaces. The cylindrical head offers a sleek appearance while ensuring strong connections. DIN 912 bolts are commonly used in mechanical engineering, automotive, and industrial equipment. They are made from durable materials like steel and stainless steel and are available in various sizes.
