Countersunk allen screw ISO 7379 M10 f9 12x70-12.9

Product detailed description

The flush-fitting screw with a cylindrical head with an internal hexagon according to ISO 7379 is designed for applications requiring a precise fit. This screw has a metric M10 thread with a diameter of 10 mm and an overall length of 70 mm. The seat has a diameter of 12 mm, which corresponds to a tolerance of f9, which guarantees a precise fit in the hole. The thread length is 16 mm, which allows sufficient grip in the material.

The screw head is cylindrical with an internal hexagon, which allows the use of a 6 mm Allen key for assembly and disassembly. The head height is 9 mm and the head diameter is 18.27 mm, which provides sufficient surface area for force transmission. The screw is made of steel of strength class 12.9, which means that it has high tensile strength and is suitable for demanding mechanical applications. This grade of steel provides a minimum tensile strength of 1220 MPa and a minimum yield strength of 1100 MPa.

The bolt is supplied without surface treatment, which is suitable for applications where corrosion protection is not required or where additional surface treatment is planned according to specific project requirements. This bolt is ideal for use in precision mechanical assemblies where it is necessary to ensure a strong and accurate connection of components, such as engineering equipment or precision instruments.
