Countersunk screw with groove DIN 963 M5x20 stainless steel A2

Product detailed description

The DIN 963 M5x20 slotted countersunk screw is made of A2 grade stainless steel, which provides high corrosion resistance, making it suitable for use in environments with higher humidity or chemical exposure. This screw has a metric thread with a diameter of M5 and a length of 20 mm, with a thread pitch of 0.80 mm.

The screw head is countersunk, which means that after installation it is flush with the surface of the material, reducing the risk of snagging and improving the aesthetic appearance of the structure. The continuous groove on the head allows the use of a standard flat screwdriver for assembly and disassembly.

The head diameter (dk) is 9.2 mm, the groove width (s) is 1.2 mm and the head height (k) is 2.5 mm. The screw complies with DIN 963, ISO 2009 and ČSN 021151 standards, which guarantees its compatibility and standardization within international applications.

This screw is ideal for applications where it is necessary to ensure a strong and reliable connection with minimal visual and physical interference with the material surface. It is suitable for use in mechanical engineering, construction and other industries where high demands are placed on the quality and durability of fasteners.
