Hexagonal lock nut for American Crane 9310

The 1056848 hexagonal lock nut is a fastening component designed to secure bolts and studs within the structural assemblies of heavy machinery. By providing a locking mechanism, this nut maintains the integrity of bolted connections that are subject to operational loads and movement. It is engineered to prevent the loosening of fasteners in critical areas of the crane, ensuring that joints remain tight and stable during operation.

This component is compatible with the American Crane 9310 and the American Hoist 9299 models. It features a 1/2-13 UNC thread specification, which corresponds to a 1/2-inch nominal diameter with 13 threads per inch. The design ensures precise fitment when used in the appropriate mounting locations throughout the crane's chassis and boom structure.

Lock nuts are used throughout heavy equipment to secure components such as undercarriage assemblies, pivot points, and structural supports. The primary function of this type of fastener is to provide resistance against loosening caused by the dynamic forces and vibrations inherent in crane operations. Proper installation of the correct thread size and type is necessary to maintain the structural safety of the machine.
