Screw cylindrical head - hex DIN 912 M8x30-8.8 galvanized

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is designed for fixed screw connections with high preload. This screw is suitable for assembly using an Allen key, which allows for efficient torque transmission and ensures a reliable connection.

The screw has a metric thread with a diameter of M8 and a pitch of 1.25 mm. The total length of the screw is 30 mm, while the thread length is 28 mm. The cylinder head has a diameter of 13 mm and a height of 8 mm, which ensures sufficient surface area for torque application. The width of the internal hexagon is 6 mm, which is a standard size for this type of screw, allowing the use of common Allen keys.

The screw material is steel of strength class 8.8, which means that it has a minimum yield strength of 640 MPa and a minimum tensile strength of 800 MPa. This strength class is suitable for applications where high mechanical resistance and reliability are required. The surface treatment is white zinc plating, which provides protection against corrosion and increases the resistance of the screw in aggressive environments.

This screw is ideal for use in various industrial sectors where high demands are placed on the strength and reliability of joints, such as mechanical engineering, the automotive industry or construction.
