Hexagon screw with partial thread DIN 931 M10x70 stainless steel A4-80

Product detailed description

Partially threaded hexagon head screw according to DIN 931, dimensions M10x70, is made of stainless steel grade A4-80. This screw is designed for applications where high corrosion resistance is required, making it suitable for use in harsh environments such as the chemical industry or marine applications.

The screw has a metric thread with a diameter of M10 and a pitch of 1.50 mm. The total length of the screw is 70 mm, with the thread covering only part of its length, which allows a firm connection to the material, while the unloaded part of the screw body provides additional strength. The hexagonal head has a width between the faces (s) of 17 mm and a width between the diagonals (e) of 19 mm, which allows the use of standard tools for assembly. The head height (k) is 6.4 mm.

The strength class A4-80 indicates that the screw has a minimum yield strength of 640 MPa and a minimum tensile strength of 800 MPa, which guarantees high mechanical resistance. The screw has no additional surface treatment, which is typical of stainless steel materials that are naturally resistant to corrosion.

This screw is suitable for fixed connections with higher stress in the areas of mechanical engineering, construction and assembly. It is compatible with ISO 4014 and ČSN 021101 standards, which ensures its versatility and the possibility of use in various international applications.
