The Genie 216634GT is a genuine OEM Top Lock Flange Nut, 7/16-20 built for Genie AL-series portable light towers, including the AL5, AL5HT, AL5 with Vertical Mast, and AL5000. As a direct OEM replacement, this nut is manufactured to the same specifications as the original hardware, ensuring a correct thread engagement and seating surface every time. Cross-reference part number 216634GT against your machine's parts manual to confirm it is the correct fastener for your unit before ordering.
Key Features
- Genuine OEM Dimensional Conformity — Manufactured to Genie OEM specifications, with correct 7/16-20 thread form and flange geometry to match the original fastener exactly.
- Top Lock Design — The top lock feature resists loosening under vibration, maintaining clamp load in service conditions typical of towable light tower equipment.
- Integrated Flange Bearing Surface — The built-in flange distributes clamping load over a wider area than a standard nut, reducing the risk of fastener pull-through or surface damage on mating components.
- Verified AL-Series Fitment — Confirmed fit for the AL5, AL5HT, AL5 with Vertical Mast, and AL5000 Genie light towers, so you can order with confidence.
- Direct Hardware Replacement — Installs in place of the original fastener with no modification to surrounding components required, keeping your repair straightforward.
A flange top lock nut combines two retention features in a single fastener: a wide, integrated flange that spreads the bearing load across the joint surface, and a top lock element that grips the bolt thread to resist loosening caused by vibration or cyclic loading. On portable light towers that are regularly towed and repositioned on jobsites, fastener integrity is critical — a nut that works loose can compromise the security of mast, frame, or component connections. Replacing a worn or damaged nut with the correct OEM part, part number 216634GT, restores the fastener joint to its original specification and maintains the structural integrity of the assembly it secures.
