The Genie 66856GT is a genuine OEM Socket Head Cap Screw, 8-32 x 3/4, Black Coat designed for Genie Z-45/25 and Z-45/25J IC Power articulating boom lifts. As a factory-sourced fastener, this screw meets the exact dimensional and material standards specified for these machines, ensuring a consistent, correct installation every time. Cross-reference part number 66856GT against your machine's parts manual to confirm it is the right fastener for your application before ordering.
Key Features
- Genuine OEM Dimensional Conformity — Sourced directly from Genie, this screw matches the exact thread pitch, head geometry, and black-coat finish specified for the Z-45/25 and Z-45/25J IC Power, ensuring it seats and torques correctly without modification.
- Black Coat Finish — The factory-applied black coating provides a surface treatment consistent with the original hardware specification, maintaining the integrity of the fastener in the assembly it serves.
- Correct 8-32 x 3/4 Thread and Length — The precise 8-32 thread form and 3/4-inch length are exactly as called out in the Genie parts manual, so there is no guesswork when replacing worn or damaged fasteners.
- Direct Fitment for Z-Series Articulating Booms — Built to serve the Z-45/25 and Z-45/25J IC Power, keeping your boom lift assembled with hardware that meets the original design intent.
- Fastener Integrity Where It Counts — A fastener that is the wrong size, thread, or specification can work loose or strip under load. Using the correct OEM screw maintains the clamping force and joint integrity the assembly was engineered to rely on.
A socket head cap screw is a precision fastener driven by an internal hex (Allen) key, allowing it to be installed in confined spaces where a standard hex-head wrench cannot reach. On articulating boom lifts such as the Z-45/25 and Z-45/25J IC Power, fasteners like this one secure covers, brackets, and structural components that must remain firmly in place throughout the machine's range of motion. A fastener that is stripped, corroded, or of the wrong specification compromises the joint it holds, which can lead to component movement or premature wear in the surrounding assembly. Replacing a damaged screw with the correct OEM part restores the joint to its original condition and keeps the machine performing as intended.
