Screw cylindrical head - hex DIN 912 M30x140-8.8

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 efficient and reliable tightening in applications where high strength and accuracy are required.

The screw has a metric thread with a diameter of M30 and a pitch of 3.50 mm. The total length of the screw is 140 mm, while the thread length is 72 mm. The cylinder head has a diameter of 45 mm and a height of 30 mm, while the width B1 is 22 mm. These dimensions are optimized to achieve maximum strength and stability in the joint.

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. The screw is supplied without surface treatment, which means that it is blackened, but without additional corrosion protection. Therefore, it is suitable for use in environments where it is not exposed to aggressive corrosive influences.

This screw is ideal for use in mechanical engineering, construction and other industrial sectors where it is necessary to ensure a strong and reliable connection of components. Its design and material properties guarantee high resistance to mechanical stress and long-term service life in demanding conditions.
