Drilled hex head bolt for American Crane 9310

The 810696 drilled hex head bolt serves as a specialized fastener for the American Crane 9310. It features a 1-1/4 inch diameter, 7 UNC thread pitch, and a 2-3/4 inch length. The head of the bolt is pre-drilled to accommodate safety wire, which prevents the fastener from loosening due to operational vibrations or movement in critical machine assemblies.

This specific hardware is intended for use in the American Crane 9310. By utilizing the safety wire hole, maintenance technicians can secure the bolt in place, ensuring that the connection remains tight during the operation of the crane. This design is commonly used in applications where maintaining fastener torque is necessary for the structural integrity of the equipment.

Hex head bolts with drilled heads are standard components used throughout heavy machinery to secure assemblies that are subject to cyclic loading. The safety wire acts as a mechanical locking device, providing a secondary method of retention to ensure that the bolt does not back out of its threaded hole during the normal duty cycle of the machine.
