Countersunk Allen screw DIN 7991 M5x12 stainless steel A4

Product detailed description

The countersunk head screw with internal hexagon according to DIN 7991 is designed for applications where a flat surface of the joint is required. This type of screw is ideal for metal and structural applications where it is necessary to ensure a strong and reliable connection. The screw has a metric thread with a diameter of M5 and a length of 12 mm, while the thread pitch is 0.80 mm.

The screw head is countersunk at an angle of 90°, which allows it to be completely embedded in the material and create a smooth surface. The head diameter (dk) is 10 mm, the head height (h) is 2.3 mm and the height k is 3.2 mm. The width of the internal hexagon (s) is 3 mm, which corresponds to the standard dimensions for this type of screw.

The screw material is A4 grade stainless steel, which provides high corrosion resistance, which is especially important in environments with high humidity or chemical aggression. The screw has no surface treatment, which is common for stainless steel materials, which already provide sufficient protection against corrosion.

The standards according to which the screw is manufactured include DIN 7991, ISO 10642 and ČSN 021144, which guarantees its compatibility and usability in international applications. This type of screw is often used in mechanical engineering, construction and other industries where high strength and reliability of joints are required.
