Screw cylindrical head - hex DIN 912 M4x110-12.9

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 effective torque transmission and ensures a reliable connection.

The screw has a metric thread with a diameter of M4 and a length of 110 mm. It is made of steel of strength class 12.9, which means that it is able to withstand high loads and is suitable for applications where high material strength is required. Strength class 12.9 indicates that the minimum yield strength is 1080 MPa and the minimum tensile strength is 1200 MPa.

The surface treatment of the screw is untreated or blackened, which means that the screw has no additional corrosion protection. Therefore, it is suitable for use in environments where it is not exposed to aggressive corrosive influences, or where additional protection is required.

The head shape is cylindrical, which allows it to be used in applications where the screw head needs to be recessed into the material. The internal hexagon (hexagon) provides high stability during assembly and disassembly, reducing the risk of damage to the screw head.

This screw is ideal for use in mechanical engineering, the automotive industry and other technical sectors where high strength and reliability of joints are required.
