Screw cylindrical head - hex DIN 912 M8x40-8.8 galvanized

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 standards 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 transmission of torque during tightening.

The screw has a metric M8 thread with a diameter of 8 mm and a pitch of 1.25 mm. The total length of the screw is 40 mm, while the thread length is 28 mm. The cylinder head has a diameter of 13 mm and a height of 8 mm, while the internal hexagon has a width of 6 mm. These dimensions correspond to standardized standards, which guarantees compatibility with commonly used components and tools.

The screw material is steel with a strength class of 8.8, which means that it has a minimum yield strength of 640 MPa and a minimum tensile strength of 800 MPa. This strength class is suitable for applications where high strength and resistance to mechanical stress are required. The screw is surface-treated with white zinc plating, which provides protection against corrosion and increases its service life in aggressive environments.

This component is ideal for use in the engineering industry, where it is necessary to ensure reliable and durable connections. Thanks to its properties, it is suitable for a wide range of applications, from structural elements to assembly assemblies, where precision and strength of the connection are important.
