Screw cylindrical head - hex DIN 912 M5x8-8.8

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 with high preload. This component is suitable for assembly using an Allen key, which allows for efficient torque transmission and ensures reliable tightening.

The screw has a metric M5 thread with a pitch of 0.80 mm, while the total thread length is 8 mm. The cylinder head has a diameter of 8.5 mm and a height of 5 mm. The width of the internal hexagon is 4 mm, which is optimized for use with conventional Allen keys.

The screw material is steel of strength class 8.8, which means that it has a yield strength of at least 640 MPa and a tensile strength of 800 MPa. The screw is supplied without surface treatment, which is suitable for applications where additional corrosion protection or aesthetic treatment is not required. If necessary, the surface can be blackened, which provides basic corrosion protection and reduces light reflection.

This screw is ideal for applications where it is necessary to achieve high preload and ensure a solid connection in structures such as machines, equipment or structural units, where accuracy and reliability of the connection are important.
