Screw cylindrical head - hex DIN 912 M20x320-10.9

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 320 mm. The thread pitch is 2.50 mm, which ensures a precise and solid connection.

The cylinder head of the screw has a diameter of 30 mm and a height of 20 mm, while the internal hexagon is adapted for use with an Allen key, which allows efficient assembly and disassembly in confined spaces. The B1 width, i.e. the distance between the hexagon surfaces, is 17 mm.

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 mechanical properties are required. The screw is supplied without surface treatment, which is important to consider when using in corrosive environments where additional protection may be required.

The thread length b is 52 mm, which provides sufficient surface area to ensure a solid connection. This screw is ideal for use in engineering, construction and other technical applications where high strength and reliability of connections are required.
