Screw cylindrical head - hex DIN 912 M12x250-8.8

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 is made of steel of strength class 8.8, which means that it has a yield strength of 640 MPa and a minimum tensile strength of 800 MPa. These properties make it suitable for use in applications where high strength and reliability of connections are required.

The screw has a thread diameter of M12 and a length of 250 mm. The head shape is cylindrical, which allows for efficient force transmission and minimizes the risk of head damage during assembly. The internal hexagon, also known as an inbus, allows the use of an Allen key, which ensures easy and precise assembly even in confined spaces.

The surface finish of the screw is untreated or blackened, which means that it is not protected against corrosion. Therefore, it is suitable for use in dry and non-corrosive environments, or where additional corrosion protection can be provided.

This screw is an ideal solution for structural applications where a strong and reliable connection of components is required. Due to its design and material properties, it is suitable for various industries, including mechanical engineering and construction.
