Key Features
- OEM-Grade Fastener Construction — Built to Genie's dimensional and thread tolerances for the 1/2-20 specification, with a nylon locking insert that meets the same material grade as the original.
- Direct OEM Replacement — Replaces the factory fastener exactly, with no rework or thread-chasing required on standard 1/2-20 threaded connections.
- Confirmed Fitment — Genuine OEM part for Genie TZ-50/30, TZ-50, TMZ-34/19, and TMZ-50/30 trailer-mounted articulating boom lifts.
- Self-Locking Design — The integrated nylon collar grips the thread under vibration and load, resisting loosening during machine operation and transport.
- Genuine Genie Part — Supplied as a genuine OEM component, so fitment accuracy and part integrity are assured right out of the packaging.
A Nylock nut uses a nylon insert at the top of the nut to create friction against the bolt thread, preventing the fastener from backing out due to vibration or repeated stress cycles. On trailer-mounted boom lifts — which are towed between jobsites and subject to road vibration as well as operational loads — fastener retention is critical to keeping structural and mechanical connections secure. A worn or missing nylon insert allows the nut to work loose over time, which can lead to play in the joint it fastens and risk damage to surrounding components. Replacing a compromised fastener with the correct OEM part restores the holding strength the original design requires.
