The Genie 121079GT is a genuine OEM Hex Head Cap Flange Screw, 1/2-13 x 3.50 built for the S-80X, S-80, and S-85 telescopic boom lifts. As a direct OEM replacement, this fastener is manufactured to the same dimensional and material standards as the original, ensuring a correct install without guesswork. Cross-reference part number 121079GT against your machine's parts manual to confirm it is the right fastener for your specific unit before ordering.
Key Features
- OEM-Grade Fastener Construction — Manufactured to Genie's original material and dimensional specifications, with the integrated flange providing consistent clamping load distribution across the joint face.
- Exact Thread and Length Spec — 1/2-13 thread pitch and 3.50-inch length match the original fastener precisely, seating correctly in the threaded bore without modification.
- Fits S-80X, S-80, and S-85 Telescopic Booms — Confirmed OEM fitment for these Genie telescopic boom lift models, so you can order with confidence.
- Structural Integrity at the Connection Point — A correctly torqued, properly spec'd fastener maintains the integrity of the joint it secures; a stripped, corroded, or wrong-spec screw risks joint movement or component separation during operation.
- Genuine Genie Part — Sourced directly through the Genie OEM supply chain, carrying the same part number used in Genie's own parts documentation.
A hex head cap flange screw combines a standard hex head cap screw with an integrated washer-style flange beneath the head. The flange spreads the clamping force over a wider area than a plain hex head screw, reducing the risk of surface damage and improving joint stability — particularly on structural connections subject to vibration or load cycling. When a fastener in this position is missing, damaged, or replaced with an incorrect substitute, the joint it secures can loosen over time, leading to component movement or wear at the mating surfaces. Using the correct OEM specification screw restores the connection to its original engineered condition.
