Key Features
- Genuine OEM Construction — Manufactured to Genie's dimensional and material specifications for the M20-2.5 thread profile, DIN439 standard, and ZAB finish, ensuring consistent engagement and holding strength.
- Exact-Fit Replacement — Matches the original fastener in thread pitch, width across flats, and height, so this nut installs directly without modification.
- Broad SX and ZX Boom Fitment — Confirmed for Genie SX super-boom telescopic lifts and ZX articulating booms, covering the SX-125 XC, SX-135 XC, SX-150, SX-180, and ZX-135/70.
- Jam Nut Locking Function — The low-profile jam nut design locks an adjacent nut in place or secures an adjustment, maintaining the correct position under vibration and load cycles common in aerial lift operation.
- Structural Integrity on Elevated Equipment — On boom lifts operating at height, a properly torqued and retained fastener is critical to maintaining the structural connections it secures; replacing a worn or damaged nut with the correct OEM part restores that assurance.
A hex jam nut is a thin, low-profile nut threaded onto a bolt or stud and tightened against another nut or surface to lock it in position. On boom lifts, jam nuts are commonly used at adjustment points and structural connections where vibration could otherwise allow a standard nut to back off over time. When a jam nut is stripped, cracked, or missing, the fastener assembly it secures can lose its set position, compromising the connection. Replacing it promptly with the correct M20-2.5 part keeps those connections properly retained.
