Key Features

- Correct Thread Specification — The 5/16-18 thread callout and GR A grade designation match the original fastener exactly, so this nut installs directly without modification or thread chasing.
- Locking Retention — The lock feature resists loosening under vibration and dynamic loads that are common on trailer-mounted boom lifts during transport and operation.
- Verified Fitment for TMZ-50/30 — Confirmed for the Genie TMZ-50/30, eliminating guesswork when sourcing a fastener replacement.
- OEM Parts Traceability — Ordering by Genie part number 65224GT ensures you receive the correct part grade and configuration for your machine's service record.
A lock nut is a fastener designed to resist self-loosening when the joint is exposed to vibration, shock loads, or cyclic movement. On a trailer-mounted articulating boom like the TMZ-50/30, fasteners throughout the structure and mechanical assemblies are subjected to continuous vibration during road transport and repetitive motion during operation. A lock nut that has lost its locking effectiveness can allow bolted connections to work loose over time, leading to play in joints, misalignment, or structural movement that would not occur with a properly secured fastener. Replacing a worn or damaged lock nut with the correct OEM-specified part restores the intended clamping force and locking performance at that connection point.
