Screw cylindrical head - hex DIN 912 M30x130-8.8

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 effective application of torque and ensures a reliable connection.

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 130 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 of the internal hexagon is 22 mm. These dimensions meet the standard requirements for this type of screw, which ensures compatibility with common applications.

The screw material is steel of strength class 8.8, which provides high tensile strength and resistance to mechanical stress. The screw is uncoated, which means it is not protected against corrosion, and is therefore suitable for use in environments where it is not exposed to aggressive conditions.

This screw is ideal for applications where high preload is required and where access to the screw head is limited, allowing the use of an Allen key. It is widely used in mechanical engineering, construction and equipment manufacturing, where precision and reliability of connections are important.
