The Genie 22790GT Socket Head Cap Screw, 1/2-13 x 3.5 is a genuine OEM fastener built for Genie Z-series articulating boom lifts, including the Z-34/22 Bi-Energy, Z-25/8, Z-20/8, and Z-20/8N. As a direct OEM replacement, this screw is manufactured to the exact thread pitch, shank diameter, and length specification required by the original design — no guesswork on sizing or substitution. It fits directly into position without any modification, making it a straightforward swap during scheduled maintenance or field repair. Always cross-reference part number 22790GT against your machine's parts manual to confirm it is the correct fastener for your specific application.
Key Features
- Exact OEM Thread Specification — 1/2-13 thread pitch and 3.5-inch length match the original fastener spec precisely, ensuring correct torque engagement and clamping load.
- Socket Head Cap Design — The recessed hex drive allows access in tight or recessed mounting locations where a standard hex head fastener may not seat cleanly.
- Genuine Genie OEM Part — Sourced directly from Genie, this screw meets the same material grade and dimensional standard as the fastener installed at the factory.
- Confirmed Fitment for Z-Series Articulating Booms — Fits the Z-34/22 Bi-Energy, Z-25/8, Z-20/8, and Z-20/8N; verify against your parts manual for your specific unit.
- Structural Integrity Where It Counts — A correctly installed, properly rated fastener maintains the clamping force that holds structural and mechanical joints together; a worn, stripped, or incorrectly sized screw compromises that joint and should be replaced immediately.
A socket head cap screw is a high-strength fastener used to secure structural, mechanical, and bracket assemblies on the machine. The socket head profile concentrates clamping force over a controlled area and allows installation with an allen key or hex driver in spaces too confined for a wrench. When a screw of this type is missing, stripped, or replaced with an incorrect size, the joint it secures can loosen under load or vibration — making it essential to replace any damaged fastener with the correct OEM part at the specified thread size and length.
