Screw cylindrical head - hex DIN 912 M20x340-10.9

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is designed for applications requiring solid screw connections with high preload. This screw has a metric thread with a diameter of M20 and a total length of 340 mm. The thread length is 52 mm, while the thread pitch is 2.50 mm.

The cylinder head of the screw has a diameter of 30 mm and a height of 20 mm, which allows for effective transmission of forces during assembly. The internal hexagon (hexagon) with a size of 17 mm is designed for use with an Allen key, which ensures easy and safe handling during assembly and disassembly.

The screw is made of steel with a strength class of 10.9, which means that it has a minimum yield strength of 900 MPa and a minimum tensile strength of 1000 MPa. This material is suitable for applications where high strength and resistance to mechanical stress are required. The screw has no surface treatment, which is important to consider in applications where it may be exposed to corrosive influences.

This type of screw is ideal for use in mechanical engineering, construction and other industries where it is necessary to ensure a reliable and strong connection of structural elements.
