Countersunk Allen screw DIN 7991 M6x25-10.9 galvanized

Product detailed description

The DIN 7991 countersunk head screw with dimensions M6x25 is made of steel of strength class 10.9, which guarantees high strength and resistance to mechanical stress. This screw is designed with an internal hexagon, which allows for efficient torque transmission during assembly and disassembly using an Allen key. The surface treatment is white zinc plating, which provides additional protection against corrosion and increases the service life of the component.

The screw has a metric thread with a diameter of M6 and a pitch of 1.00 mm, which is a standard configuration for this type of fastener. The total length of the screw is 25 mm, while the countersunk head has a height of 2.5 mm and a diameter of 12 mm, which allows the head to be recessed into the material to achieve a flat surface of the joint. The head height is 3.7 mm and the width of the internal hexagon is 4 mm, which is optimized for standard Allen keys.

The angle of the countersunk head is 90°, which is typical for this type of screw and ensures a strong and aesthetically clean connection without protruding parts. The screw is ideal for use in metal and structural applications where a strong and reliable connection with minimal visual interference is required. The ISO 10642 and ČSN 021144 standards guarantee compatibility and standardization within international and national regulations.
