Button head screw for Liebherr LTM 1070-4.1

The button head screw is a precision fastening component used to secure various panels, access covers, and internal cabin components within the Liebherr LTM 1070-4.1 mobile crane. Its low-profile, rounded head design minimizes protrusions, making it suitable for assemblies where clearance is limited or where a flush finish is required to prevent snagging. The screw conforms to the ISO 7380-2 standard and features a property class of 10.9, indicating its mechanical strength characteristics for use in heavy machinery environments.

This component is specified for the Liebherr LTM 1070-4.1, ensuring correct fitment and alignment during maintenance or repair procedures. The screw dimensions are M4 x 12 mm. Proper installation and adherence to torque specifications are necessary to maintain the integrity of the fastened assemblies and to prevent loosening caused by the operational vibrations and dynamic loads typical of crane operation.

Fasteners of this type are used throughout mobile cranes to join structural or protective elements. By providing a secure connection point, they ensure that covers and control panels remain fixed in position during the rigorous duty cycles of the machine.
