Countersunk allen screw ISO 7379 M8 f9 10x10-12.9

Product detailed description

The flush-mounted screw with a cylindrical head and internal hexagon according to ISO 7379 is designed for applications where precise assembly and high connection strength are required. This particular model has a metric M8 thread with a diameter d of 8 mm and a thread pitch of 1.25 mm. The total length of the screw is 10 mm, while the thread length b is 13 mm, which allows for sufficient hold in the material.

The cylindrical head of the screw has a diameter dk of 16.27 mm and a height k of 7 mm, while the internal hexagon has a width s of 5 mm, which ensures effective torque transmission during assembly. The screw is made of steel of strength class 12.9, which means that it has a very high tensile strength and is suitable for demanding mechanical applications. This grade of steel is capable of withstanding high loads without deformation or damage.

The surface of the screw is untreated, which means that it is not protected against corrosion, and is therefore suitable for use in dry or controlled environments where it is not exposed to moisture or chemicals. The screw is designed for a precise fit with the shoulder, which ensures stability and accuracy of the assembly, and is comparable to the DIN 9841 standard, which defines similar design features.

This screw is ideal for use in mechanical engineering where a reliable and precise connection is required, for example in the assembly of machine parts, where the accuracy and strength of the connection are critical.
