Cap screw for National Crane 900

The cap screw 7115140678 serves as a fastener within the National Crane 900 crane assembly. It is engineered to secure various mechanical and structural components, maintaining the integrity of the machine's connections during operation. This fastener is designed to hold parts firmly together, ensuring stability across the crane's systems.

This component is specified for the National Crane 900 model. It is manufactured to Grade 5 standards with a 1/4 inch - 20 NC thread specification and a 3/4 inch length. Grade 5 fasteners are defined by a minimum tensile strength of 120,000 psi and a yield strength of 92,000 psi, providing the necessary mechanical properties for securing critical assemblies.

Cap screws are threaded fasteners used to join machine components by passing through a clearance hole in one part and threading into another. They provide a clamping force that keeps assemblies aligned and secure against operational loads and vibrations. Regular inspection of these fasteners is necessary to ensure they remain tightened to the correct torque specifications and are free from signs of wear or deformation.
