Key Features
- Genuine OEM Thread and Locking Specification — Manufactured to Genie's exact 7/8-9 Z thread specification with a nylon insert that delivers consistent locking retention under vibration and load cycling common on towable light towers.
- Direct OEM Replacement — Matches the original fastener geometry and thread form exactly, dropping into place without modification or additional hardware.
- Broad Light Tower Compatibility — Fits multiple Genie and Terex portable light tower models, including the RL4000, TML-4000, AL5 with Vertical Mast, and RL4 series variants.
- Nylon Insert Locking Performance — The nylock design resists loosening caused by machine vibration during transport and operation, maintaining fastener clamp load over time.
- OEM Parts Confidence — Sourced directly through the Genie OEM supply chain, so the part number, dimensions, and material grade match what the machine was built with.
A Nylock nut uses a nylon insert at the top of the nut to grip the bolt thread and resist self-loosening under vibration — a critical property on towable equipment like light towers that experience road vibration during transport and continuous engine vibration during operation. When a standard or worn fastener loses its locking ability, joint clamp load drops and structural connections can work loose over time. Replacing a fastener with the correct OEM-specified Nylock Nut, 7/8-9 Z restores the intended clamping and locking performance for that connection point.
