Screw cylindrical head - hex DIN 912 M4x22-10.9

Product detailed description

The cylinder head screw with internal hexagon, designated according to DIN 912, ISO 4762 and ČSN 021143 standards, is intended for fixed screw connections with high preload. This component is suitable for assembly using an Allen key, which is inserted into the internal hexagon of the screw head, which allows for efficient torque transmission and minimizes the risk of head damage during assembly.

The screw has a metric thread with a diameter of M4 and a pitch of 0.70 mm. The total length of the screw is 22 mm, while the thread length is 20 mm. The cylinder head has a diameter of 7 mm and a height of 4 mm. The width of the internal hexagon is 3 mm, which corresponds to the standardized dimensions for this type of screw.

It is made of steel of strength class 10.9, which means that the screw has a minimum tensile strength of 1,000 MPa and a minimum yield strength of 900 MPa. This high strength class ensures that the screw is suitable for applications where high mechanical resistance and reliability are required. The screw is supplied without surface treatment, which must be taken into account when used in environments with higher humidity or chemical aggressiveness, where additional corrosion protection may be required.

This type of screw is widely used in mechanical engineering and construction, where it is necessary to ensure strong and reliable joints. It is ideal for applications where precision and joint strength are important, such as in the automotive industry, machine building or in the production of various mechanical devices.
