Countersunk Allen screw DIN 7991 M5x12-10.9

Product detailed description

The DIN 7991 M5x12-10.9 Allen countersunk screw is a structural element designed for applications requiring a solid and reliable connection with a flat surface finish. This type of screw is characterized by a countersunk head with an internal hexagon, which allows it to be embedded in the material so that the surface remains smooth and without protrusions.

The screw has a metric thread with a diameter of M5 and a length of 12 mm, while the thread pitch is 0.80 mm. The screw head is designed with an angle of 90°, which is standard for countersunk screws, and its diameter is 10 mm. The head height is 2.3 mm, while the width of the internal hexagon is 3 mm, which allows the use of a standard Allen key for assembly.

The screw material is steel with a strength class of 10.9, which means that the screw has high tensile strength and is suitable for demanding mechanical applications. The screw has no surface treatment, which must be taken into account when using it in a corrosive environment.

This screw is manufactured according to DIN 7991, which is equivalent to ISO 10642 and ČSN 021144, which guarantees its compatibility and interchangeability in international applications. Thanks to its properties, it is ideal for use in metal and structural applications where a strong and aesthetically clean connection is required.
