Countersunk screw with groove DIN 963 M8x30 galvanized

Product detailed description

The countersunk screw with a groove according to DIN 963, size M8x30, is made of steel of strength class 4.8. This screw is characterized by a countersunk head, which allows for aesthetic and flush joints, with the head being completely recessed into the surface of the material. The groove is continuous, which means that it runs the entire width of the head and allows the use of a standard flat screwdriver.

The screw has a metric thread with a diameter of M8 and a pitch of 1.25 mm, with the thread extending to the head of the screw. The total length of the screw is 30 mm. The head diameter (dk) is 14.5 mm and the head height (k) is 4 mm, which corresponds to the standard dimensions for this type of screw.

The surface treatment is made with white zinc plating, which provides protection against corrosion and increases resistance to external influences. This screw is suitable for use in both metal and plastic parts where an aesthetic appearance and a strong connection are required. The ISO 2009 and ČSN 021151 standards are equivalent to DIN 963, which ensures international compatibility and standardization.
