Screw cylindrical head - hex DIN 912 M12x190-12.9

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is designed for applications requiring high strength and reliability. This screw has a metric M12 thread with a length of 190 mm and is made of steel of strength class 12.9, which guarantees high mechanical resistance and the ability to transmit significant preload. Strength class 12.9 indicates that the screw has a minimum yield strength of 1080 MPa and a minimum tensile strength of 1200 MPa, which makes it suitable for use in demanding industrial applications.

The cylinder head of the screw is equipped with an internal hexagon, which allows for easy and efficient assembly using an Allen key. This type of head is ideal for applications where the height of the head above the joint surface needs to be minimized, or where access to the head is limited. The screw is supplied without surface treatment, which means that it is in a basic black finish. This condition is suitable for applications where additional corrosion protection is not required, or where subsequent surface treatment is planned according to specific project requirements.

This screw is suitable for fixed screw connections in mechanical engineering, the automotive industry, construction and other areas where high demands are placed on the strength and reliability of the connections. Its use is particularly suitable in situations where it is necessary to achieve high preload in the connection, thereby increasing the overall stability and safety of the structure.
