Countersunk Allen screw DIN 7991 M3x12-10.9 galvanized

Product detailed description

The DIN 7991 M3x12-10.9 zinc-plated countersunk head screw is designed for applications requiring a strong and reliable connection with a flat surface finish. This screw is made of 10.9 strength steel, which guarantees high strength and resistance to mechanical stress. The zinc-plated surface treatment provides protection against corrosion, thus extending the life of the component in harsh conditions.

The screw has a metric thread with a diameter of M3 and a length of 12 mm. The thread pitch is 0.50 mm, which is standard for this type of thread. The screw head is countersunk with an internal hexagon, which allows it to be embedded in the material and create a smooth surface without protrusions. The head angle is 90°, which is typical for countersunk screws according to DIN 7991, ISO 10642 and ČSN 021144.

The head diameter (dk) is 6 mm, the head height (k) is 1.86 mm and the countersunk height (h) is 1.2 mm. The width of the internal hexagon (s) is 2 mm, which allows the use of a standard Allen key for assembly and disassembly.

This screw is ideal for metal and structural applications where an aesthetically clean and functional joint needs to be ensured. It is suitable for use in industrial sectors where high demands are placed on the strength and reliability of the joints.
