Key Features

• Correct Thread and Grip Specification — The 1/2-13 thread pitch and 4.5-inch length match the OEM specification exactly, threading cleanly into existing tapped holes without chasing or modification.
• Broad Genie Fitment — Fits S-60 and S-65 XC telescopic booms alongside the full GTH telehandler range including GTH-636, GTH-844, GTH-1056, GTH-1244, GTH-1256, and GTH-1544 models.
• Genuine OEM Part — Supplied directly under the Genie part number 1256107GT, confirming it meets the dimensional and material standards set at the time of original manufacture.

A hex head cap screw is a fully threaded or partially threaded fastener used to secure structural and mechanical assemblies on the machine. The hex head allows a wrench or socket to apply the correct installation torque, while the specified grade and length ensure the joint holds under the dynamic loads these machines experience during operation. Using a fastener with the wrong grade, thread pitch, or length can result in an under-strength joint, thread stripping, or improper clamping force — any of which can lead to premature component failure. Replacing a worn or damaged fastener with the correct OEM specification part restores the joint to its designed clamping strength and keeps the assembly secure.
