Key Features
- Genuine OEM Construction — Correct thread form, dimensional tolerancing, and ZAG finish as specified by Genie, ensuring the nut seats and locks exactly as intended.
- Direct Replacement Fit — Matches the original 5/16-18 thread spec, so this nut installs in the same position as the part it replaces without modification.
- Wide Equipment Compatibility — Fits Genie GS scissor lifts, GTH series telehandlers, and Z-34/22 articulating boom lifts, covering multiple equipment families with a single part number.
- Locking Retention — A jam nut is tightened against a primary fastener or adjustment to prevent loosening under vibration and dynamic loading — replacing a worn or damaged one restores that clamping integrity.
- Long-Term Fastener Reliability — OEM-grade hardware resists corrosion and maintains clamping force through extended service cycles, reducing the risk of fastener failure between scheduled maintenance intervals.
A jam nut is a thin nut threaded against a standard nut or a fixed point to lock a fastener assembly in position and prevent it from backing off under vibration or repeated loading. On aerial lifts and telehandlers, jam nuts are commonly used on adjustment points, linkages, and structural connections where a precise, locked setting must be maintained over time. When a jam nut is loose, missing, or damaged, the fastener it secures can shift out of adjustment or work free entirely, affecting the integrity of the assembly it holds. Replacing it promptly with the correct OEM part keeps that connection secure and the machine's adjustments where they were set.
