The Genie 1254728GT Jam Nut, 5/8-11, A, ZAG is a genuine OEM fastener built for Genie SX-125 XC super-boom telescopic lifts, GS-1330m scissor lifts, and Z-62/40 articulating boom lifts. As a direct OEM replacement, this jam nut carries the exact thread specification and finish of the original, so it seats and locks as intended without any reworking of the mating hardware. Cross-reference part number 1254728GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Genuine OEM Dimensional Conformity — Manufactured to Genie's original specification, with the correct 5/8-11 thread profile, grade, and ZAG finish to match the fastener it replaces.
- Direct Thread-for-Thread Replacement — The matching thread pitch and nut geometry allow this fastener to seat flush against its mating component exactly as the original did.
- Verified Fitment Across Multiple Machine Families — Confirmed for Genie SX-125 XC telescopic booms, GS-1330m scissor lifts, and Z-62/40 articulating booms.
- Secure Locking Performance — A jam nut installed correctly holds its position against vibration and cyclic loading, keeping the fastener stack tight throughout normal machine operation.
A jam nut is a thin nut threaded against a standard nut or a fixed point to lock both in place and prevent them from backing off under vibration or repeated movement. On aerial lift equipment, fasteners like this appear throughout structural assemblies, pivot points, and adjustable linkages where maintaining a precise and stable connection is critical. A jam nut that has loosened, corroded, or been lost will allow the mating hardware to shift, which can affect alignment, create play in a joint, or allow further fastener loss — making prompt replacement with the correct OEM part the straightforward fix.
