Screw cylindrical head - hex DIN 912 M6x85-12.9

Product detailed description

The cylinder head screw with internal hexagon, also known as an Allen screw, is manufactured according to DIN 912, ISO 4762 and ČSN 021143. This component is designed for applications requiring high preload in bolted joints, which is achieved thanks to the high strength of the material. The screw has a metric thread M6 and a length of 85 mm.

The material of the screw is steel of strength class 12.9, which means that it has a very high tensile strength, namely at least 1200 MPa. This strength class is suitable for critical applications where high load-bearing capacity and resistance to mechanical stress are required. The screw is supplied without surface treatment, which means that it is in a raw state or blackened, which can be important for certain applications where corrosion must be prevented or where a specific aesthetic appearance is required.

The cylindrical head of the screw allows for even pressure distribution on the surface of the material into which the screw is fastened. The internal hexagon provides a reliable hold for an Allen key, which allows for efficient torque transmission during assembly or disassembly. This type of head is particularly suitable for applications where space is limited for the use of traditional tools.

The screw is ideal for use in mechanical engineering, the automotive industry and other technical areas where reliable and strong connections are required. It is important to adhere to the recommended assembly torques when using it to ensure optimal functionality and safety of the connection.
