Screw cylindrical head - hex DIN 912 M4x12-10.9

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 screw is made of steel with strength class 10.9, which guarantees high strength and resistance to mechanical stress. The screw does not have a surface treatment, which is important to consider when using it in an environment with the possibility of corrosion.

The screw has a metric thread with a diameter of M4 and a pitch of 0.70 mm. The total length of the thread is 12 mm. The cylinder head has a diameter of 7 mm and a height of 4 mm, while the internal hexagon allows assembly using an Allen key, which simplifies handling and increases assembly efficiency.

The use of this screw is suitable in applications where high strength of joints is required, such as mechanical structures, the automotive industry or other technical equipment. It is important to ensure correct preload during assembly to achieve optimal functionality and longevity of the joint.
