Countersunk screw with groove DIN 963 M2x20 stainless steel A2

Product detailed description

The DIN 963 slotted countersunk head screw, size M2x20, is made of A2 grade stainless steel. This component features a countersunk head that allows the screw to be recessed into the material so that its head is flush with the surface, ideal for applications where a smooth surface without protrusions is required.

The thread diameter is M2, which means that the metric thread has an outer diameter of 2 mm. The screw length is 20 mm, which is the distance from the bottom of the head to the end of the thread. The screw has a metric thread pitch of 0.40 mm, which is the distance between the threads.

The screw head has a countersunk shape with a continuous groove that allows the use of a standard flat screwdriver for installation or removal. The groove width is 0.5 mm and the head height is 1.2 mm. The head diameter (dk) is 3.8 mm, which provides sufficient surface area for torque transmission.

The A2 stainless steel material provides the screw with high corrosion resistance, making it suitable for use in environments with higher humidity or outdoors. The screw has no additional surface treatment, which is common for stainless steel components that already provide sufficient corrosion protection on their own.

This screw is suitable for applications where aesthetics and functionality are important, such as in the furniture industry, electronics or precision mechanics. The ISO 2009 and ČSN 021151 standards guarantee that the screw meets international and national quality and dimensional standards.
