Screw cylindrical head - hex DIN 912 M12x70-12.9

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 screw is made of steel with strength class 12.9, which guarantees high tensile strength and resistance to mechanical stress. The screw has no surface treatment, it is blackened, which provides basic protection against corrosion in less demanding conditions.

The dimensions of the screw are as follows: the nominal thread diameter is M12, the total length of the screw is 70 mm, while the thread length is 36 mm. The head diameter is 18 mm, the width of the groove for the internal hexagon is 10 mm and the head height is 12 mm. The screw has a metric thread with a pitch of 1.75 mm, which is standard for this type of thread.

This component is suitable for assembly using an Allen key, which allows for efficient torque transmission and simplifies assembly in confined spaces. The screw is ideal for use in mechanical engineering, the automotive industry and other areas where high strength and reliability of connections are required.
