DHS Equipment stocks this part for straightforward ordering and fast fulfillment.
Key Features
- OEM-Grade Fastener Material — Grade 2 hardware with a nylon locking insert molded to dimensional spec, delivering the clamping and retention performance the original design requires.
- Nylon Lock Insert for Vibration Resistance — The integrated nylon collar grips the thread under vibration, reducing the risk of fastener loosening over the service life of the machine.
- Exact 1/2-13 Thread Specification — The 1/2-13 UNC thread matches the original threaded fastener location directly, with no modification to mating hardware needed.
- Broad Light Tower Compatibility — Fits a wide range of Genie and Terex portable light towers, including AL4, AL4000, AL4L, AL5, AL5HT, AL5L, RL4, RL4 LED Vertical Mast, RL4000, RL4 Vertical Mast, AL5 with Vertical Mast, and TML-4000.
- Genuine OEM Part — Carrying the Genie 990200GT part number, this nut is a genuine OEM component — not a generic substitute — so you can cross-reference it confidently against your parts manual.
A Nylock nut uses a nylon insert at the top of the nut to create friction against the bolt thread, locking the fastener in place even when the joint is subject to vibration or repeated movement. This self-locking action prevents the nut from backing off without the need for a separate lock washer or thread-locking compound. A loose or missing nut at a structural or mounting location can allow panels, guards, or components to shift, so replacing worn or damaged hardware with the correct OEM part — cross-referenced as part number 990200GT against your machine's parts manual — keeps the assembly secure and properly torqued.
