Screw cylindrical head - hex DIN 912 M12x40-8.8

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 type of 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 M12 and a pitch of 1.75 mm. The total length of the screw is 40 mm, while the thread length is 36 mm. The cylinder head has a diameter of 18 mm and a height of 12 mm, while the width of the internal hexagon is 10 mm. These dimensions are in accordance with the above standards, which ensures compatibility and versatility of use in various applications.

The screw material is steel with a strength class of 8.8, which means that it has a minimum yield strength of 640 MPa and a minimum tensile strength of 800 MPa. The screw is supplied without surface treatment, which is referred to as blackening, and is suitable for applications where additional corrosion protection is not required.

This screw is ideal for use in engineering, construction and other industries where it is necessary to ensure a strong and reliable connection of components. Thanks to its design and material properties, it provides high resistance to mechanical stress and is suitable for applications with high loads.
