Sheet metal screw for Liebherr LTM 1070-4.1

This sheet metal screw, part number 40 82 808 08, serves as a fastening component to secure metal panels and protective covers on the Liebherr LTM 1070-4.1 mobile crane. These panels protect internal machine systems, including electrical and hydraulic components, from external elements. The fastener is designed to create its own thread during installation, which allows for efficient assembly and maintenance of the crane bodywork.

The component adheres to the ISO 7051 standard with a thread diameter of 4.8 mm and a length of 13 mm. It is specified as ST C-H A2C, indicating the head type and material composition suitable for the assembly requirements of the LTM 1070-4.1 model. Proper installation ensures that access panels remain firmly attached during crane operation and transport.

In heavy machinery, sheet metal screws are used to attach housing, guards, and trim pieces to the frame or chassis. These fasteners are selected based on their thread pitch and head design to ensure they remain seated despite the vibrations inherent in crane operation. Using the correct fastener size maintains the integrity of the protective enclosures that shield the machine's internal systems from environmental debris and moisture.
