Screw cylindrical head - hex DIN 912 M8x70-8.8

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 type of screw is suitable for assembly using an Allen key, which allows for easy and efficient installation even in confined spaces. The screw has a metric thread with a diameter of M8 and a pitch of 1.25 mm, which guarantees a reliable connection in various applications.

The screw is structurally equipped with a cylinder head with a diameter of 13 mm and a height of 8 mm, which provides sufficient contact surface for even pressure distribution. The internal hexagon with a diameter of 6 mm allows the use of a standard Allen key for assembly. The screw length is 70 mm, while the thread length is 28 mm, which allows sufficient screwing depth for a firm fit.

The screw material is steel with a strength class of 8.8, which means that the screw has high tensile strength and is suitable for demanding mechanical applications. The surface finish is untreated or blackened, which provides basic corrosion protection and increases the component's service life in less aggressive environments.

This screw is ideal for use in industrial applications where high strength and reliability of joints are required, such as mechanical engineering, the automotive industry or equipment manufacturing. Its design features and material composition guarantee long-term functionality and resistance to mechanical stress.
