Key Features
- Genuine OEM Fastener Grade — Manufactured to Genie's original material and dimensional spec for an M12X1.75 Nylock Nut, delivering the correct clamping load and thread engagement every time.
- Nylon-Insert Locking — The integrated nylon collar resists vibration-induced loosening, keeping critical fastened joints secure across the full duty cycle of a boom lift.
- Exact-Match Threading — M12X1.75 thread pitch matches the original hardware exactly, so this nut seats and torques correctly without rework or adaptation.
- Broad Boom Lift Coverage — Fits Genie SX super-boom telescopic lifts and ZX and TMZ articulating booms, including XC variants and trailer-mounted models.
- Structural Integrity at Height — On aerial boom lifts, a fastener that loosens or fails can compromise the structural integrity of joints under load — using the correct OEM-spec nut is a straightforward way to maintain that integrity.
A Nylock nut is a standard hex nut fitted with a nylon insert at the top of the thread. When tightened, the nylon collar deforms slightly around the bolt threads, creating friction that prevents the nut from backing off under vibration or cyclical loading. This self-locking characteristic makes it the preferred fastener in applications where joints are subject to movement, shock, or repeated stress — conditions common on boom lift structures and assemblies. A missing, stripped, or incorrect nut allows the joint to work loose over time, which can lead to misalignment, accelerated wear on surrounding components, or structural failure at the connection point. Replacing a worn or damaged fastener with the correct Genie OEM specification nut restores the joint to its original clamping condition.
