Countersunk Allen screw DIN 7991 M5x12-8.8

Product detailed description

The DIN 7991 M5x12-8.8 countersunk head screw is designed for applications where a flat surface of the joint is required. This screw is made of steel of strength class 8.8, which guarantees high strength and reliability of the connection. Its design allows it to be used in metal and structural applications where high resistance to mechanical stress is required.

The main distinguishing feature of this screw is the countersunk head with an internal hexagon, also known as an Allen key. This design allows the screw head to be recessed into the material, achieving a smooth surface without protruding parts. The internal hexagon with a size of 3 mm allows for effective torque transmission during assembly and disassembly using an Allen key.

The screw has a metric thread with a diameter of M5 and a pitch of 0.80 mm. The thread length is 12 mm, which is suitable for connections where medium thread depth is required. The countersunk head has a diameter of 10 mm and a height of 2.3 mm, while the total height of the screw including the head is 3.2 mm. The angle of the countersunk head is 90 degrees, which is the standard angle for this type of screw according to DIN 7991, ISO 10642 and ČSN 021144.

The screw is supplied without surface treatment, which is suitable for applications where additional corrosion protection is not required. If necessary, the screw can be additionally modified according to specific surface treatment requirements. This screw is ideal for use in environments where high connection strength and aesthetic embedding into the material are required.
