The Genie 824038GT is a genuine OEM Top Lock Jam Nut, 3/8-16, A, ZAG built for a wide range of Genie equipment including S and SX telescopic boom lifts, GS scissor lifts, Z and ZX articulating boom lifts, and GTH telehandlers. As a direct OEM replacement, this nut is manufactured to the same specifications as the original hardware installed at the factory, ensuring correct thread engagement and finish. Part number 824038GT covers an extensive cross-section of Genie machines, making it a frequently needed fastener across mixed fleets. Always cross-reference 824038GT against your machine's parts manual to confirm it is the correct item for your specific unit and serial number.
Key Features
- Genuine OEM Specification — Manufactured to Genie's original dimensional and finish standards, including the correct ZAG zinc alloy finish and grade-A material rating for reliable thread integrity.
- Correct Thread Form — 3/8-16 UNC thread form matches the original fastener exactly, seating flush without rework or thread chasing.
- Broad Fleet Coverage — Fits Genie S and SX telescopic booms, GS scissor lifts, Z and ZX articulating booms, and GTH telehandlers, reducing the number of fastener SKUs needed on a mixed fleet.
- Locking Design — The top lock jam nut profile resists loosening under vibration and dynamic loading, maintaining clamp force during machine operation.
- Direct OEM Source — Supplied as a genuine Genie part through DHS Equipment, so provenance and part identity are certain before it goes on the machine.
A jam nut is a thin nut threaded onto a fastener or stud and tightened against a primary nut or bearing surface to prevent that nut from rotating loose under load or vibration. The top lock variant adds a locking feature at the top of the nut to increase resistance to loosening in applications where cyclic movement or vibration is present. When a jam nut backs off or is missing, the fastened joint loses its clamping force, which can allow components to shift, wear unevenly, or work free entirely. Replacing a worn or missing jam nut with the correct OEM part — part number 824038GT in the 3/8-16 size — restores the joint to its intended clamped condition.
