Screw cylindrical head - hex DIN 912 M12x20-10.9

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 thread is 20 mm, which corresponds to the total length of the screw. 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 optimized for use in applications where high strength and reliability of the connection are required.

The screw material is steel with a strength class of 10.9, which means that the screw 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 mechanical properties are required. The screw is supplied without surface treatment, which is suitable for applications where additional corrosion protection is not required or where further surface treatment is expected.

This screw is ideal for use in engineering, construction and other industrial applications where it is necessary to ensure a strong and reliable connection with high resistance to mechanical stress.
