Screw cylindrical head - hex DIN 912 M8x40-10.9 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 increases the reliability of the 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 40 mm, while the thread length is 28 mm. The cylinder head has a diameter of 13 mm and a height of 8 mm, which provides sufficient space for applying torque. The width of the internal hexagon is 6 mm, which is optimized for the use of a standard Allen key.

The screw material is steel with a strength class of 10.9, which means that it has a minimum yield strength of 900 MPa and a minimum tensile strength of 1000 MPa. This strength class is suitable for applications where high strength and resistance to dynamic loads are required. The surface treatment is white zinc plating, which provides corrosion protection and increases the service life of the component in aggressive environments.

This screw is ideal for use in mechanical engineering, the automotive industry and other industries where reliable and strong screw connections are required. Its design features and standards ensure compatibility with various industrial applications and standards.
