The Genie 121078GT is a genuine OEM Flange Hex Head Cap Screw, 3/8-16x2.5 built for Genie S-80 and S-85 telescopic boom lifts. As a direct OEM replacement, this screw is manufactured to the exact thread pitch, shank diameter, and length specified for the application, so it seats and torques correctly without modification. Cross-reference part number 121078GT against your machine's parts manual to confirm it is the correct fastener for your specific assembly before ordering.
Key Features
- Genuine OEM Specification — Produced to Genie's exact material grade, thread form, and dimensional tolerances, ensuring proper clamping load and thread engagement for this fastener application.
- Correct Thread and Length — The 3/8-16 thread and 2.5-inch shank length match the original fastener exactly, so the screw fits the mating threads without rework or substitution.
- Integrated Flange Design — The flange distributes clamping load across a wider bearing surface, reducing the need for a separate washer and maintaining consistent joint integrity over time.
- Compatible with S-80 and S-85 Booms — Verified fitment for Genie S-80 and S-85 telescopic boom lifts, so you can order with confidence for these machines.
- Structural Joint Integrity — A correctly torqued, properly sized fastener keeps structural and mechanical joints secure; a worn, stripped, or mismatched screw can allow movement and accelerate wear in the connected components.
A flange hex head cap screw combines a standard hex head cap screw with a built-in flange beneath the head. The flange acts like an integrated washer, spreading the clamping force over a larger surface area to protect the mating material and maintain a secure, stable joint. When a fastener of this type is missing, damaged, or replaced with an incorrect size, the joint it secures may loosen under vibration or load, leading to movement in the assembled components and potential accelerated wear. Using the correct OEM screw with the right thread pitch, length, and material grade ensures the joint performs as designed throughout the service life of the machine.
