Countersunk Allen screw DIN 7991 M6x65-10.9 galvanized

Product detailed description

The countersunk screw with internal hexagon according to DIN 7991, ISO 10642 and ČSN 021144 is designed for applications requiring precise fit and high preload. This component has a metric M6 thread with a length of 65 mm and a partial thread with a length of 18 mm. The screw is made of steel with a strength class of 10.9, which guarantees high tensile strength and resistance to mechanical stress. The surface treatment is made with white zinc plating, which provides protection against corrosion.

The screw head has a countersunk shape with an angle of 90°, which allows it to be embedded in the material so that it is flush with the surface, thus achieving an aesthetic and functional joint. The head height is 2.5 mm, the width of the internal hexagon is 4 mm and the total head diameter is 12 mm. The height of the conical part of the head is 3.7 mm. These dimensions are optimized for applications where it is necessary to minimize the protrusion of the screw above the surface.

The screw is suitable for use in structures where it is necessary to ensure a strong and reliable connection with minimal aesthetic disturbance of the surface. The internal hexagon allows for efficient transmission of torque during assembly and disassembly, which is advantageous in applications with limited access. The screw is ideal for use in mechanical engineering, the automotive industry and other technical industries where high demands are placed on the strength and accuracy of the connections.
