Countersunk screw with groove DIN 963 M8x40 galvanized

Product detailed description

The DIN 963 countersunk screw with a groove, with dimensions M8x40, is made of steel of strength class 4.8 and is surface-treated with white zinc. This screw is characterized by a countersunk head, which allows for aesthetic and flush joints, with the head being flush with the surface of the material after installation. This type of head is suitable for applications where a smooth surface without protruding parts is required.

The screw has a metric thread with a diameter of M8 and a length of 40 mm, with the thread extending the entire length to the head. The thread pitch is 1.25 mm. The diameter of the countersunk head is 14.5 mm, the head height is 4 mm and the groove width is 2 mm. The groove is continuous, which allows the use of a standard flat screwdriver for assembly and disassembly.

The DIN 963 standard is equivalent to the ISO 2009 and ČSN 021151 standards, which guarantees compatibility and standardization on an international scale. The screw is suitable for use in both metal and plastic parts where a strong and reliable connection is required. The zinc coating provides corrosion protection, which extends the life of the screw in various environments.
