Countersunk Allen screw DIN 7991 M10x30-8.8

Product detailed description

The DIN 7991 M10x30-8.8 Allen countersunk screw is a structural element 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. Thanks to the countersunk head with an internal hexagon, also known as an Allen, the screw can be recessed into the material so that its head does not protrude above the surface, which is ideal for aesthetic and functional applications in metal and structural assemblies.

The screw has a metric thread with a diameter of M10 and a length of 30 mm. The thread pitch is 1.50 mm, which is standard for this type of thread. The countersunk head has a diameter of 20 mm and a height of 4.4 mm, while the total height of the screw including the head is 6.2 mm. The angle of the countersunk head is 90°, which corresponds to DIN 7991, ISO 10642 and ČSN 021144. The internal hexagon has a width of 6 mm, which allows the use of a standard Allen key for assembly and disassembly.

This screw is supplied without surface treatment, which means that it is suitable for applications where additional corrosion protection is not required, or where additional surface treatment is expected according to specific project requirements. The screw is ideal for use in various industrial sectors where it is necessary to ensure a strong and reliable connection with minimal visual and physical interference with the material surface.
