Cap screw for National Crane 900

The cap screw 7115204450 serves as a fastener for securing structural and mechanical components within the National Crane 900 crane. It is manufactured to Grade 5 specifications, which designates a medium-strength carbon steel construction suitable for load-bearing applications. The fastener measures 5/8 inch in diameter with an 11 UNC thread pitch and a total length of 5 1/2 inches.

This component is specifically engineered for fitment on the National Crane 900 crane model. It provides the necessary mechanical connection for various assemblies where precise thread engagement and tensile strength are required to maintain the structural integrity of the machine. The Grade 5 rating ensures that the fastener meets defined standards for tension and yield strength under operational conditions.

Cap screws are threaded fasteners used to join machine parts by passing through clearance holes and threading into a tapped component. They are commonly utilized in heavy machinery to secure structural members, mounting brackets, and housing assemblies. Proper selection of thread size and grade is necessary to ensure that the joint maintains its clamping force and resists the mechanical stresses encountered during crane operation.
