Screw cylindrical head - hex DIN 912 M8x20-10.9 galvanized

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 suitable for assembly using an Allen key, which allows for efficient torque transmission and ensures secure fastening of components.

The screw has a metric thread with a diameter of M8 and a pitch of 1.25 mm. The total thread length is 20 mm, which meets the standard requirements for this type of fastener. The cylinder head of the screw has a diameter of 13 mm and a height of 8 mm, while the internal hexagon has a width of 6 mm, which is optimized for use with conventional Allen keys.

The screw material is steel with a strength class of 10.9, which means that the screw has high tensile strength and is suitable for demanding applications where high reliability of the connection is required. The surface treatment is made with white zinc, which provides protection against corrosion and increases the resistance of the screw in aggressive environments.

This screw is ideal for use in mechanical engineering, the automotive industry and other areas where high demands are placed on the strength and reliability of joints. Its design and material properties guarantee long-term functionality and resistance to mechanical stress.
