Square head bolt for P&H CX25976

The 20F314D1 square head bolt functions as a critical fastening component within the brake assembly of heavy-duty P&H cranes. It is specifically engineered to provide a secure anchor and adjustment point for the springs that manage the tension and release of the 19-inch brake mechanism. Proper tensioning of these springs is required for the brake system to engage and release effectively during lifting operations.

This component is compatible with P&H crane models CX25976 and CX25977. The bolt features a 7/8-inch UNC thread diameter, a total length of 13-1/2 inches, and is manufactured to Grade 2 specifications. The square head design facilitates a secure grip for precise mechanical adjustments during maintenance procedures.

In heavy machinery, bolts of this type serve as the primary mechanical interface for tensioning springs and securing linkages within braking or clutch systems. By maintaining the specified thread pitch and length, these fasteners ensure that the spring force is applied consistently across the brake assembly, which is necessary for the controlled operation of the crane's load-handling systems.
