Screw cylindrical head - hex DIN 912 M18x35-12.9

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 a strength class of 12.9, which guarantees high tensile strength and resistance to mechanical stress. The screw has a metric thread with a diameter of M18 and a pitch of 2.50 mm, while the total thread length is 35 mm.

The cylinder head of the screw has a diameter of 27 mm and a height of 18 mm, which allows for effective transmission of forces during tightening. The internal hexagon allows the use of an Allen key, which simplifies assembly and disassembly in confined spaces. The B1 width, which is relevant for the use of a key, is 14 mm. The screw is supplied without surface treatment, but can be blackened to increase corrosion resistance.

This screw is suitable for applications in mechanical engineering, where high demands are placed on the strength and reliability of the connections. It is ideal for use in structures where it is necessary to ensure high preload and resistance to dynamic stress.
