Screw cylindrical head - Allen DIN 912 M18x55-8.8 galvanized

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is intended for fixed screw connections with high preload. This screw is designed for assembly using an Allen key, which allows for efficient torque transmission and reduces the risk of damage to the screw head during assembly.

The screw has a metric thread with a diameter of M18 and a pitch of 2.50 mm. The total length of the screw is 55 mm, while the thread length is 48 mm, which ensures sufficient screwing depth for a stable connection. The cylinder head has a diameter of 27 mm and a height of 18 mm, while the width of the internal hexagon is 14 mm, which is optimized for use with conventional Allen keys.

The material of the screw 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. This strength class is suitable for applications where it is necessary to ensure high mechanical resistance and reliability of the connection. The screw is surface-treated with white zinc plating, which provides protection against corrosion and increases its resistance in harsh environments.

This screw is ideal for use in engineering, construction and other industrial sectors where connections with high strength and corrosion resistance are required. Thanks to its technical parameters and quality processing, it is suitable for a wide range of applications where a reliable and durable connection is required.
