Key Features
- Genuine OEM Construction — Manufactured to Genie's exact dimensional and material specifications, ensuring proper thread engagement and holding strength for the fastening application.
- Direct OEM Replacement — This nut installs directly in place of the original, with no modification needed to match the 5/8-11 thread spec.
- Broad GS Series Fitment — Compatible with the GS-3384, GS-3390, GS-4390, and GS-5390 scissor lifts; verify against your parts manual before ordering.
- Jam Nut Design — The low-profile jam nut profile is engineered to lock a primary nut in position, resisting loosening under vibration and dynamic load.
- Corrosion-Resistant Finish — ZAG (zinc) finish provides a protective coating that helps the fastener resist corrosion in outdoor and demanding jobsite environments.
A jam nut is a thin, low-profile nut threaded onto a bolt or stud and tightened against a primary nut to prevent it from backing off under vibration or movement. On scissor lifts like the GS-3384 and GS-5390, fasteners in structural and mechanical assemblies are subject to repeated load cycles, and a loosened or missing jam nut can allow critical joints to shift or fail. Replacing a worn or damaged jam nut with the correct OEM part restores the locking function and keeps the fastened assembly secure during operation.
