Screw cylindrical head - hex DIN 912 M8x220-12.9

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is intended for applications where it is necessary to achieve high preload in the screw connection. This screw has a metric thread M8 and a length of 220 mm, which makes it suitable for use in structures where a longer screw with high strength is required.

The screw material 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 demanding applications where the screws are exposed to high mechanical loads. The screw is supplied without surface treatment, which means that it is in a black state, and is therefore suitable for use in environments where additional corrosion protection or aesthetic treatment is not required.

The cylindrical head of the screw allows for efficient torque transmission using an Allen key, which simplifies assembly and disassembly in confined spaces. The internal hexagon ensures reliable tool retention and minimizes the risk of head damage when applying high torque.

This screw is ideal for use in mechanical engineering, the automotive industry and other industries where high demands are placed on the strength and reliability of connections. It is important to ensure the correct preload during assembly to achieve optimal functionality and service life of the connection.
