Screw cylindrical head - hex DIN 912 M4x110-8.8

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is designed for applications requiring strong screw connections with high preload. This screw has a metric thread M4 and a length of 110 mm, which makes it suitable for use in structures where a longer screw is needed to ensure a reliable connection.

It is made of steel of strength class 8.8, which means that it has a yield strength of approximately 640 MPa and a tensile strength of approximately 800 MPa. Such a strength class is suitable for medium-demanding applications where high strength and resistance to mechanical stress are required. The screw is supplied without surface treatment, which means that it is in a basic black finish, and is therefore suitable for use in environments where additional corrosion protection is not required.

The cylindrical head of the screw allows for efficient torque transmission using an Allen key, which simplifies assembly and disassembly in confined spaces. The internal hexagon ensures a firm hold of the tool, minimizing the risk of damage to the head when applying torque.

This screw is ideal for use in mechanical engineering, the automotive industry and other areas where high demands are placed on the reliability and strength of connections. It is suitable for applications where high preloads need to be achieved, as well as for structures where precision and stability of the connection are important.
