Description

M5x30 black countersunk socket screw 10.9, DIN7991 is designed for structural joints where a clean, flat surface without protruding elements is required. Thanks to its high tensile strength class 10.9, it provides excellent tensile and shear resistance, making it an ideal choice for stressed machine parts.

The fastener with a total length of 30 mm features an M5 partial thread with a length of 16 mm. This design allows for secure clamping of the connected parts together, while the smooth portion of the shank helps with precise alignment in the drilled hole.

Technical Advantages and Details

Countersunk hex socket head: Allows the screw to be flush-mounted into the material surface with the possibility of tight fastening using a 3 mm key.
High-tensile steel 10.9: Guarantees a stable joint that resists vibration and higher operating loads.
DIN 7991 / ISO 10642 certification: Defines precise dimensions and facilitates reliable interchangeability during maintenance.
Unfinished surface: The black surface is suitable for lubricated environments or for components that will be fully painted after assembly.

When preparing the joint, I recommend paying attention to the precise angle and depth of the countersink so that the 2 mm high head seats perfectly. A carefully prepared pocket ensures a clean appearance and eliminates unwanted local stress in the material.
