Screw with half-round head hex ISO 7380 M8x50 steel 10.9 zinc

Product detailed description

The hemispherical head screw with internal hexagon according to ISO 7380 is designed with a metric thread M8 and a length of 50 mm. This type of screw is made of steel of strength class 10.9, which guarantees high strength and resistance to mechanical stress. The surface treatment is made of white zinc plating, which provides protection against corrosion and increases the service life of the component in harsh conditions.

The screw head has a hemispherical shape with a diameter dk of 14 mm, which allows for an even distribution of pressure on the surface of the material into which the screw is fastened. The head height is 4.4 mm, while the internal hexagon with a size of 5 mm allows for effective transmission of torque during assembly and disassembly. The thread pitch is 1.25 mm, which is standard for metric threads of this size, ensuring a strong and reliable connection.

This screw is ideal for applications where high connection strength and corrosion resistance are required, such as in mechanical engineering, the automotive industry or in structures where aesthetics and functionality of the connections are important. The internal hexagon makes assembly and disassembly easy and fast, which reduces the time required for maintenance and service.
