Screw cylindrical head - hex DIN 912 M5x80-8.8

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 requiring high preload. This screw has a metric thread with a diameter of M5 and a pitch of 0.80 mm. The total length of the screw is 80 mm, while the thread length is 22 mm. The cylinder head has a diameter of 8.5 mm and a height of 5 mm, while the internal hexagon is designed for use with an Allen key, which allows efficient assembly and disassembly in confined spaces.

The screw is made of 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 material provides sufficient strength for most standard applications where high reliability and resistance to mechanical stress are required. The screw is not surface-treated, which means it is blackened, and is therefore suitable for use in environments where increased corrosion resistance is not required.

This screw is ideal for use in mechanical engineering, the automotive industry and other technical applications where it is necessary to ensure a strong and reliable connection of components. Thanks to the internal hexagon, it is possible to achieve high preload during assembly, which increases the overall stability and safety of the connection.
