Screw cylindrical head - hex DIN 912 M30x340-12.9

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 screw has a metric thread with a diameter of M30 and a total length of 340 mm. The thread pitch is 3.50 mm, which ensures a precise and solid connection. The thread length is 72 mm, which allows sufficient screwing for secure fastening.

The screw head is cylindrical in shape with an internal hexagon (hexagon), which allows assembly using an Allen key. The head diameter is 45 mm, the width B1 is 22 mm and the head height H is 30 mm. This head design provides high strength and resistance to deformation when applying high torque.

The screw is made of steel with a strength class of 12.9, which means that it has a very high tensile strength and is suitable for applications where maximum resistance to mechanical stress is required. The surface finish is untreated or blackened, which can provide basic protection against corrosion, however, for environments with high humidity or chemical aggressiveness, additional surface treatment is recommended.

This screw is ideal for use in industrial applications where high strength and reliability connections are required. It is suitable for assembly and maintenance of machines, equipment and structures where a strong and durable connection is required.
