Hex head cap screw for National Crane 900

The hex head cap screw 864289 serves as a standard fastening component for the National Crane 900 crane. Its hexagonal head design allows for the application of torque using standard wrenches or sockets, ensuring a firm connection between joined parts. This component is used in critical assembly points of the crane, including the chassis sections, boom supports, and slewing system components, where maintaining a secure union is necessary for structural integrity.

This part is compatible with the National Crane 900 crane, including units with serial number 293854. It is engineered to meet the specific fastening requirements of this crane model, providing the necessary tension for structural joints. Proper installation and torque application are required to ensure the stability of the assemblies where this screw is utilized.

Hex head cap screws are used throughout heavy machinery to join structural members and mechanical housings. They allow for the disassembly of components during maintenance procedures while maintaining the required clamping force when tightened to the manufacturer specifications. Regular inspection of these fasteners is standard practice to ensure that all structural connections remain tight and secure during crane operation.
