Screw cylindrical head - Allen DIN 912 M12x250-12.9

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 has a metric thread with a diameter of M12 and a length of 250 mm, which makes it suitable for a wide range of industrial and mechanical applications.

It is made of steel of strength class 12.9, which means that it offers high tensile strength and resistance to mechanical stress. Steel of grade 12.9 is able to withstand a minimum tensile stress of 1200 MPa, which makes it suitable for use in demanding conditions where high reliability of connections is required.

The screw is without surface treatment, which means that it has no additional corrosion protection, and is therefore suitable for use in environments where it is not exposed to corrosive influences, or where additional protection is provided. The surface may be black, which is the result of the heat treatment process.

The cylindrical head with an internal hexagon allows for easy assembly and disassembly using an Allen key, which increases efficiency and accuracy during assembly. This type of head is particularly suitable for applications where tool space is limited, as the internal hexagon minimizes the need for space around the screw head.

This screw is ideal for use in mechanical engineering, the automotive industry and other areas where high demands are placed on the strength and reliability of connections.
