Screw cylindrical head - Allen DIN 912 M30x65-8.8

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is designed for applications requiring strong screw connections with high preload. This particular screw has a metric thread with a diameter of M30 and a length of 65 mm. It 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 screw is without surface treatment, which means that it is not protected against corrosion, and is therefore suitable for use in environments where it is not exposed to corrosive influences or additional surface treatment is required.

The cylinder head of the screw allows for efficient transmission of torque when installing using an Allen key, which is practical for applications with limited space for tools. The internal hexagon ensures a reliable hold of the key and reduces the risk of damage to the head during installation or removal. This bolt is commonly used in mechanical engineering, construction, and equipment manufacturing where high strength and reliability of joints are required.
