The Genie 1251713GT is a genuine OEM TL Nylock Nut, M12-1.75, DIN980, 10, ZAB built for Genie SX telescopic boom lifts and ZX articulating boom lifts, including the SX-150, SX-180, SX-135 XC, SX-125 XC, and ZX-135/70. As a direct OEM replacement, this nut meets the exact dimensional and material standards required for these machines. Cross-reference part number 1251713GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- OEM-Grade Material and Thread Conformity — Manufactured to DIN980 standard in strength class 10 with ZAB finish, matching the original fastener spec for these boom lifts.
- M12-1.75 Thread Specification — The M12-1.75 thread pitch is integral to this nut's identity, ensuring it seats correctly on the mating fastener without modification.
- Nylon-Insert Locking Action — The nylon lock element resists vibration-induced loosening, maintaining clamp load during the duty cycles typical of large telescopic and articulating boom operation.
- Broad SX and ZX Boom Coverage — Fits the SX-150, SX-180, SX-135 XC, SX-125 XC, and ZX-135/70, covering Genie's tallest telescopic and heavy-duty articulating boom models.
- Genuine Genie OEM Part — Sourced directly from Genie, ensuring the correct part reaches your machine without the risk of dimensional mismatches common with non-OEM fasteners.
A Nylock nut uses a nylon collar insert at the top of the nut that deforms around the bolt threads when tightened, creating resistance that prevents the nut from backing off under vibration and dynamic loading. On large boom lifts like the SX and ZX series — which experience significant movement and load cycling during extension, articulation, and travel — fastener retention is critical to structural integrity. A loose or missing nut at key connection points can lead to joint movement, accelerated wear on surrounding components, or loss of structural holding force. Replacing a worn or damaged fastener with the correct OEM specification nut restores proper clamping and keeps the assembly performing as designed.
