Countersunk screw with groove DIN 963 M3x12 galvanized

Product detailed description

The countersunk head screw with a continuous groove according to DIN 963, with dimensions M3 x 12 mm, is made of steel of strength class 4.8. This screw is characterized by its countersunk head, which allows for aesthetic and flush joints, with the head being flush with the surface of the material after countersinking. The continuous groove on the screw head is designed for flat-blade screwdrivers, which allows for easy assembly and disassembly.

The entire thread of the screw, which extends to the head, is metric with a pitch of 0.50 mm, which guarantees a strong and reliable connection. The thread diameter is M3, which means that the outer diameter of the thread is 3 mm. The length of the screw is 12 mm, which is the distance from the end of the thread to the bottom of the head. The head diameter (dk) is 5.6 mm, the head height (k) is 1.65 mm and the groove width (s) is 0.8 mm.

The screw material is treated with white zinc plating, which provides increased corrosion resistance and improves its service life in environments with higher humidity. The screw is suitable for use in metal and plastic parts where an aesthetic appearance and precise fit are required. ISO 2009 and ČSN 021151 standards guarantee that the screw meets international quality and dimensional standards. This screw is ideal for applications where it is necessary to ensure a strong, reliable and aesthetically pleasing connection.
