Countersunk Allen screw DIN 7991 M5x8-10.9

Product detailed description

The DIN 7991 M5x8-10.9 Allen countersunk screw is a mechanical fastener designed for applications where a flat surface is required. This screw is manufactured according to DIN 7991, which is equivalent to ISO 10642 and ČSN 021144, and is characterized by its countersunk head with an internal hexagon, which allows the head to be recessed into the material and create a smooth surface.

The screw has a metric thread with a diameter of M5 and a length of 8 mm. The head height is 2.3 mm and the head diameter is 10 mm, while the countersunk angle is 90 degrees. The internal hexagon has a width of 3 mm, which allows the use of a standard Allen key for assembly and disassembly. The screw has a metric thread pitch of 0.80 mm, which is standard for this type of thread.

The screw material is steel with a strength class of 10.9, which means that it has a high tensile strength and is suitable for applications where high mechanical resistance is required. The screw is supplied without surface treatment, which can be important in applications where additional surface treatment is required according to specific requirements.

This screw is ideal for metal and structural applications where it is necessary to achieve a strong and reliable connection with an aesthetically smooth surface. Due to its design features, it is suitable for use in various industries, including mechanical engineering and construction.
