Screw cylindrical head - hex DIN 912 M22x60-12.9

Product detailed description

The cylinder head screw with internal hexagon, also known as the Allen screw, is manufactured according to DIN 912, ISO 4762 and ČSN 021143 standards. This type of screw is intended for fixed screw connections that require high preload and is suitable for assembly using an Allen key. The screw has a metric thread with a diameter of M22 and a length of 60 mm. The total length of the thread is 56 mm, while the thread pitch is 2.50 mm.

The cylinder head of the screw has a diameter of 33 mm and a height of 22 mm. The width B1, which indicates the space for the Allen key, is 17 mm. The screw is made of steel with a strength class of 12.9, which means that it has a high tensile strength, namely at least 1220 MPa. This parameter is important for applications where the screws are exposed to high mechanical loads.

The surface treatment of the screw is without additional treatment, which means that it is blackened. This type of surface treatment provides basic protection against corrosion and is suitable for applications where high demands are not placed on resistance to corrosion. The screw is ideal for use in mechanical engineering and industrial applications where it is necessary to ensure a reliable and strong connection of components.
