Screw cylindrical head - hex DIN 912 M27x160-12.9

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is designed for applications requiring high strength and reliability. This particular screw has a metric thread M27 with a total length of 160 mm and a thread pitch of 3.00 mm. The thread diameter is 27 mm and the outer diameter of the head is 40 mm. The head height is 27 mm, while the width of the internal hexagon is 19 mm, which allows the use of an Allen key for assembly.

The screw is made of steel with a strength class of 12.9, which means that it has a very high tensile strength, namely at least 1200 MPa, and a yield strength of at least 1080 MPa. This type of steel is suitable for applications where it is necessary to achieve high preload in the bolted joint. The surface finish of the screw is without additional treatment, which means that it is blackened, which provides basic protection against corrosion.

The thread length on the screw is 66 mm, which allows sufficient grip in the material. The screw is suitable for use in engineering, construction and other industrial applications where a strong and reliable connection needs to be ensured. Thanks to the internal hexagon, assembly is simple and efficient, while allowing the application of high torque without the risk of damaging the screw head.
