Key Features
- Genuine OEM Fastener — Manufactured to Genie's original dimensional and material specifications, so this nut threads and torques exactly as the factory intended.
- Nylon Insert Locking Design — The nylon insert grips the mating thread under vibration, resisting loosening over time without requiring thread-locking compounds or additional hardware.
- Direct OEM Replacement — Installs in place of the original with no rework, fitting all connection points specified for part number 991945GT.
- Built for Genie AL-Series Light Towers — Confirmed fitment for the AL5000, AL5HT, AL5, and AL5 with Vertical Mast, covering the core AL5 product family.
- Consistent Clamping Integrity — A secure, correctly torqued fastener maintains structural connections on the light tower, preventing movement or wear at bolted joints during transport and operation.
A nylon insert lock nut is a prevailing-torque fastener that uses a nylon collar embedded in the top of the nut to create friction against the bolt thread, keeping the nut from backing off under vibration or repeated movement. On light towers that are regularly towed, repositioned, and raised, fastener integrity at structural and mechanical joints is essential to safe, reliable operation. A missing or worn lock nut allows connected components to shift or loosen, which can accelerate wear at the joint and compromise the assembly it secures. Replacing a damaged or missing nut with the correct OEM part restores the clamping force the joint was designed to hold.
