Countersunk head screw for Liebherr LTM 1070-4.1

The 12 22 03 75 countersunk head screw serves as a mechanical fastener used to secure various components within the assembly of heavy machinery. Its design allows the head to sit flush with or below the surface of the material, which prevents surface obstructions and ensures a clean profile across the mounting area. This type of fastener is commonly utilized in structural joints where a low-profile connection is required to maintain the integrity of the machine's external or internal panels.

This component is specifically engineered for the Liebherr LTM 1070-4.1 mobile crane. It adheres to the ISO 10642 standard for countersunk screws with an internal hex drive. The fastener measures M8 in diameter with a length of 20 mm and is manufactured to an 8.8 strength class, providing the necessary mechanical properties for its intended application in the crane's structure.

Countersunk screws are essential for maintaining the alignment and secure attachment of panels and covers across various crane systems. By ensuring that the fastener head does not protrude, these screws help maintain the structural geometry and clearance requirements of the equipment during operation.
