Screw cylindrical head - Allen head DIN 912 M20x260-12.9

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is designed for applications requiring high preload in bolted joints. This screw has a metric thread with a diameter of M20 and a length of 260 mm, which makes it suitable for use in structures where high strength and reliability of joints are required.

It is made of steel of strength class 12.9, which means that it has a minimum tensile strength of 1200 MPa and a minimum yield strength of 1080 MPa. These mechanical properties guarantee that the screw is able to withstand high loads without plastic deformation. The surface of the screw is without special treatment, which means that it is blackened, which provides basic protection against corrosion and is suitable for applications where increased resistance to corrosive influences is not required.

The screw head is cylindrical with an internal hexagon, which allows the use of an Allen key for assembly and disassembly. This type of head is popular in mechanical engineering and industrial production, as it allows the application of a high torque when tightening while minimizing the risk of damage to the screw head. The screw is ideal for use in areas where it is necessary to ensure a strong and permanent connection of components, such as mechanical structures, mechanical equipment and other technical applications.
