Countersunk screw with groove DIN 963 M5x40 galvanized

Product detailed description

The countersunk slotted screw according to DIN 963 and ISO 2009 is designed for applications where aesthetic appearance and precise fitting of joints are required. This screw has a metric thread with a diameter of M5 and a length of 40 mm, with the thread extending to the screw head. The shape of the head is countersunk, which allows it to be aligned with the surface of the material into which the screw is installed, thus achieving a smooth surface without protruding parts.

The screw head is equipped with a continuous slot, which is designed for use with a flat screwdriver. This type of slot is common for applications where easy assembly and disassembly are required. The head height is 2.5 mm and the head diameter is 9.2 mm, which provides sufficient surface area for effective torque transfer during tightening.

The screw is made of steel of strength class 4.8, which means that it has a yield strength of 320 MPa and a tensile strength of 400 MPa. This strength class is suitable for common mechanical applications where extreme strength requirements are not imposed. The surface treatment is zinc-plated, specifically white zinc, which provides protection against corrosion and improves the aesthetic appearance of the screw.

The screw is suitable for use in metal and plastic parts where aesthetic and precise fit is required. It is ideal for applications in mechanical engineering, electrical engineering and other industrial sectors where a combination of functionality and appearance is important.
