Hexagonal drilled bolt for American Crane 9310

The 812289 hexagonal drilled bolt serves as a critical fastening component within the American Crane 9310. This hardware is engineered with a specific drilled head to accommodate safety wire, which prevents the fastener from loosening during operation. By securing the bolt with wire, maintenance teams ensure the connection remains stable even when subjected to the dynamic loads and vibrations common in heavy lifting equipment. It is typically utilized in structural assemblies, counterweight systems, or undercarriage components where secure fastening is required for operational safety.

This component is manufactured to precise dimensions, featuring a 5/8-11 UNC thread specification and a total length of 1-1/2 inches. It is designed to fit the American Crane 9310 crane model. When installing this bolt, ensure the thread pitch and length match the requirements of the specific assembly to maintain the integrity of the joint.

Drilled bolts are used in machinery to provide a locking mechanism that standard fasteners cannot offer. By threading safety wire through the head of the bolt and anchoring it to an adjacent point, the fastener is physically restricted from rotating. This method is standard practice in heavy machinery to maintain torque settings in high-vibration environments.
