The Genie 121430GT is a genuine OEM Flange Head Screw, M10 x 70 GR12.9, built for Genie S-80 and S-85 series telescopic boom lifts. As a genuine OEM part, it is manufactured to the exact dimensional and grade specifications Genie requires, ensuring consistent performance in its designed application. This screw fits the S-80X, S-80, S-85, S-80 XC, S-85 XC, S-80 HF, and S-85 HF — cross-reference part number 121430GT against your machine's parts manual to confirm it is the correct fastener for your unit before ordering.
Key Features
- Grade 12.9 High-Strength Fastener — GR12.9 classification means this screw meets demanding tensile and proof-load requirements, suited for high-stress structural connections on heavy aerial equipment.
- Integrated Flange Head Design — The flange distributes clamping load over a wider bearing surface, reducing the need for a separate washer and providing a more secure, consistent joint.
- Exact OEM Dimensions — M10 x 70 threading and head geometry conform to the precise specifications Genie calls out for this application, so the screw seats and torques correctly without modification.
- Broad S-Series Compatibility — Fits a range of S-80 and S-85 telescopic boom lift variants, including XC and HF models, covering multiple configurations within the same family.
- Structural Integrity Matters — A fastener that is the wrong grade, size, or thread pitch can work loose or fail under load. Using the correct OEM-specified screw maintains the joint integrity that aerial lift service and inspection standards depend on.
A flange head screw is a threaded fastener with a wide, integrated washer-like collar beneath the head that spreads clamping force across a broader surface area than a standard hex head screw. On large telescopic boom lifts such as the S-80 and S-85 series, structural fasteners are selected for specific grade and length requirements to handle the loads present in their mounting locations. Using a fastener of the correct grade — in this case GR12.9, one of the highest strength classes in the metric fastener system — ensures the joint maintains its designed clamping force over time. A worn, stripped, or incorrect-grade screw in a load-bearing location can allow movement between components, leading to accelerated wear or structural loosening that requires prompt attention.
