The Genie 45066GT Socket Head Cap Screw, 5/8-11 x 2.25 is a genuine OEM fastener built for Genie S series telescopic boom lifts, Z series articulating boom lifts, and GS series scissor lifts. As a genuine OEM part, this screw is manufactured to the same specification as the original hardware installed at the factory, ensuring dimensional accuracy and thread compatibility right out of the box. Fitment includes models such as the S-40, S-45, S-60, S-65, S-80, S-85, GS-3390, GS-4390, GS-5390, Z-30/20 N, Z-34/22 IC, Z-34/22 Bi-Energy, Z-34 IC, Z-45/22, and Z-60/34 — cross-reference part number 45066GT against your machine's parts manual to confirm the correct application before ordering.
Key Features
- Genuine OEM Thread Integrity — Manufactured to exact thread pitch and dimensional tolerances for a 5/8-11 x 2.25 socket head cap screw, eliminating fitment guesswork.
- Direct Hardware Replacement — Drops into the original fastener position with no rework needed; the socket head drive accepts a standard hex key for installation and removal.
- Broad Genie Equipment Compatibility — Fits S series telescopic booms, Z series articulating booms, and GS series scissor lifts across a wide range of model variants.
- Secure Clamping Force — A correctly installed screw maintains the clamping load that holds structural and mechanical assemblies in position; a worn, stripped, or missing fastener compromises joint integrity and should be replaced promptly.
- Structural Safety Relevance — On aerial work platforms, fastener condition directly affects the integrity of load-bearing and structural joints — using the correct OEM-spec replacement is essential for safe operation.
A socket head cap screw is a high-strength threaded fastener driven by an internal hex socket rather than an external wrench flat. The socket head profile allows the screw to seat in counterbored or close-clearance locations where a standard hex bolt head would not fit, making this style common in structural and mechanical assemblies on aerial equipment. When a screw in this application is lost, cross-threaded, or no longer holds torque, the joint it secures can loosen under load — replacing it with the correct OEM fastener restores the clamping integrity the assembly was designed around.
