Self-tapping screw for Liebherr LTM 1070-4.1

The self-tapping screw, identified by part number 40 82 019 08, serves as a critical fastening element for securing non-structural components within the Liebherr LTM 1070-4.1 mobile crane. This component is engineered to create its own thread upon insertion, which simplifies the assembly of various covers, access panels, and electrical mounting points throughout the machine. By providing a secure connection, it ensures that these auxiliary parts remain firmly in place during crane operations.

This fastener adheres to the ISO 7049 standard and features dimensions of ST4.8x25, with a cylindrical head and internal hex drive. It is specifically intended for use on the Liebherr LTM 1070-4.1, where it is utilized to maintain the integrity of protective housings and interior cabin elements. The finish is designated as A2C, providing the necessary surface protection for the application environment.

Self-tapping screws are commonly used in heavy machinery to secure components where traditional machine screws are not required. Their ability to form threads in the base material allows for efficient assembly and maintenance, particularly when securing sheet metal or plastic panels. Using the correct fastener ensures that vibrations encountered during crane operation do not compromise the fitment of protective covers or electrical enclosures.
