The M12x40 Allen bolt, grade 8.8, is made of hardened steel with a tensile strength of 800 MPa and complies with the 8.8 class standard. The thread diameter is 12 millimeters and the overall bolt length is 40 millimeters, providing a secure connection for high-load components. The internal hex socket head allows easy installation with an Allen wrench and enables assembly in confined spaces. Threads are manufactured with ISO 68-2 precision, ensuring a shear strength of 640 MPa. The bolt surface is corrosion-resistant or zinc-coated, and a dimensional tolerance of ±0.1 millimeters enhances durability and connection quality.

The M12x40 Allen bolt is suitable for connecting metal, plastic, and composite components in industrial and automotive structures. The thread angle is 60 degrees, with a recommended installation torque of 70 Nm and tensile load capacity of 8.8 kN. Production according to DIN 912 standard ensures dimensional uniformity and quality of the hex socket head. The bolt can be installed with a hand or socket wrench and is suitable for dry or lubricated industrial environments. Controlled hardness of HRC 32-36 and an effective thread length of 35 millimeters guarantee a reliable connection and long service life of components.
