Screw cylindrical head - hex DIN 912 M3x22-8.8

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is designed for applications requiring strong screw connections with high preload. This type of screw has a metric thread with a diameter of M3 and a length of 22 mm. The main structural element is a cylinder head with internal hexagon, which allows assembly using an Allen key, which provides effective torque transmission and minimizes the risk of head damage when tightening.

The screw is made of steel of strength class 8.8, which means that it has a yield strength of 640 MPa and a tensile strength of 800 MPa. This material ensures high mechanical resistance and reliability in demanding conditions. The surface of the screw is without special treatment, which means that it is in a basic black finish, providing basic corrosion protection, suitable for applications in less aggressive environments.

This screw is ideal for use in mechanical engineering, where it is necessary to ensure a strong and reliable connection of components. It is suitable for use in various industrial sectors, where precision and high resistance of joints are required.
