The Genie 123143GT is a genuine OEM Nylock Nut, 1-8, GR8 built for Genie S-60 telescopic boom lifts, Z-45 and Z-51 articulating boom lifts, and GTH-1056 telehandlers. As a genuine OEM part, it is manufactured to the exact specifications Genie requires, ensuring the correct thread pitch, grade, and locking performance wherever it is used on the machine. Cross-reference part number 123143GT against your machine's parts manual to confirm this is the correct fastener for your application before ordering.
Key Features
- Integrated Nylon Locking Element — The nylon insert resists vibration-induced loosening, helping fastened joints hold their torque through continuous machine operation and rough terrain use.
- Exact OEM Thread Specification — The 1-8 thread callout matches the OEM-specified pitch exactly, ensuring full thread engagement with no need for modification.
- Broad Genie Family Fitment — Fits Genie S-60 telescopic booms, Z-45 and Z-51/30J articulating booms, and the GTH-1056 telehandler, covering multiple equipment families from a single part number.
- Genuine OEM Part — Sourced directly from Genie, this fastener meets the same material and dimensional standards as the hardware originally installed on the machine.
A Nylock nut uses a nylon insert at the top of the threaded bore to grip the bolt shank and resist rotation caused by vibration or dynamic loading. Unlike a standard hex nut that can back off under repeated movement, the locking element keeps the nut in place without the need for thread-locking compounds or secondary locking hardware. On aerial lifts and telehandlers, fasteners are subjected to constant vibration and load cycling, so using a correctly graded, correctly sized replacement is essential to maintaining the integrity of the joint. A loose or incorrect fastener at a structural or mechanical connection point can allow unwanted movement between components, leading to premature wear or joint failure.
