Countersunk Allen screw DIN 7991 M12x60-8.8 galvanized

Product detailed description

The DIN 7991 M12x60-8.8 zinc-plated countersunk head screw is a high-precision fastener designed for applications requiring a reliable and aesthetically clean connection. This screw is made of steel of strength class 8.8, which guarantees high strength and resistance to mechanical stress. The zinc-plated surface treatment provides protection against corrosion, thereby extending the life of the component in various environments.

The screw has a metric thread with a diameter of M12 and a length of 60 mm. The thread pitch is 1.75 mm, which is standard for this type of screw and allows for a precise and strong connection. The countersunk head with an internal hexagon (hexagon) allows the screw to be embedded in the material so that its head is flush with the surface, which is ideal for applications where a flat surface of the connection is required. The head diameter (dk) is 24 mm, the head height (k) is 7.4 mm and the countersunk height (h) is 4.6 mm. The countersunk head angle is 90°, which corresponds to the standards for this type of screw.

The screw meets the standards DIN 7991, ISO 10642 and ČSN 021144, which guarantees its compatibility and usability in international applications. The 8 mm internal hexagon allows the use of standard Allen keys, which facilitates assembly and disassembly. This screw is ideal for metal and structural applications where it is necessary to achieve a strong and reliable connection with minimal visual disturbance of the surface.
