Key Features
- Genuine OEM Conformity — Manufactured to Genie's dimensional and grade specifications, ensuring this serrated nut seats and torques exactly as the original.
- Serrated Flange Design — The serrated bearing face bites into the mating surface to resist loosening under vibration, providing a more secure hold than a standard nut.
- Broad Genie Fitment — Compatible across Genie GS scissor lifts, S and Z series booms, and GTH telehandlers, covering a wide range of machines in a single part number.
- Direct OEM Replacement — Sourced directly from Genie, this nut installs in place of the original without modification, keeping your repair straightforward and your machine back in service.
A serrated nut is a flanged fastener with teeth machined into the underside of the flange. When tightened, those teeth embed into the clamping surface and lock the nut against rotational movement caused by vibration or repeated load cycling. On mobile equipment like boom lifts, scissor lifts, and telehandlers, vibration is constant, and a fastener that works loose can allow structural joints or component brackets to shift. Using the correct grade and thread specification — 5/16-18, Grade 8 — ensures the fastener delivers the clamping force the joint was designed around. A worn, stripped, or incorrect nut in these positions should be replaced promptly with part number 1255805GT to maintain the integrity of the assembly.
