Screw cylindrical head - hex DIN 912 M8x130-8.8 galvanized

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. The screw has a metric thread with a diameter of M8 and a pitch of 1.25 mm. The total length of the screw is 130 mm, while the thread length is 28 mm. The screw is made of steel of strength class 8.8, which means that it has a minimum yield strength of 640 MPa and a minimum tensile strength of 800 MPa. The surface treatment is white zinc plating, which provides basic protection against corrosion.

The cylinder head of the screw has a diameter of 13 mm and a height of 8 mm. The internal hexagon, also known as the hexagon, has a width of 6 mm, which allows the use of an Allen key for assembly and disassembly. This design allows for efficient torque transmission and is ideal for applications where high preload in the joint is required. The screw is suitable for use in various industrial sectors where a reliable connection with high strength and resistance to mechanical stress is required.

The screw is part of the category of fasteners, namely screws with internal hexagon, and is widely used in mechanical engineering, the automotive industry and other technical fields. Its design features and standardized dimensions ensure compatibility with other components and systems that require precise and reliable connections.
