Sheet metal screw for Liebherr LTM 1070-4.1

The 10 87 57 93 sheet metal screw is a self-tapping fastener used to secure various non-structural components within the Liebherr LTM 1070-4.1 mobile crane. It is specifically engineered to join metal or plastic panels, access covers, and auxiliary equipment housings. The part follows the ISO 7049 standard, featuring a cross-recessed head design that allows for efficient installation using standard hand or power tools. This fastener ensures that panels remain firmly in place, protecting internal systems from environmental exposure and preventing vibration-induced loosening during crane operation.

This component is specified for the Liebherr LTM 1070-4.1 all-terrain crane. It features a nominal diameter of 4.2 mm and a length of 9.5 mm. The self-tapping thread profile is designed to create its own thread in the mating material, providing a secure connection without the need for pre-tapped holes. Proper installation of these fasteners is necessary to maintain the integrity of the crane's exterior panels and internal protective covers.

Sheet metal screws of this type serve as the primary attachment method for non-load-bearing assemblies in heavy machinery. By creating a tight fit against the mounting surface, they prevent the rattling of panels and ensure that protective covers remain correctly aligned over the machine's internal components.
