Screw cylindrical head - hex DIN 912 M8x65-8.8

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 M8 thread with a length of 65 mm and a pitch of 1.25 mm. The thread length is 28 mm, which is optimal for ensuring a fixed connection in various applications. The cylindrical head has a diameter of 13 mm and a height of 8 mm, while the internal hexagon has a width of 6 mm, which is standard for this type of screw and allows the use of common Allen keys.

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. Such mechanical properties are suitable for applications where high strength and resistance to dynamic loads are required. The screw is supplied without surface treatment, which means that it is blackened, and is therefore suitable for use in environments where it is not exposed to corrosive influences.

This screw is ideal for use in mechanical engineering, the automotive industry and other industries where it is necessary to ensure strong and reliable screw connections. Its design features and the standards according to which it is manufactured guarantee high quality and compatibility with other components within the framework of international standards.
