The Genie 1257075GT is a genuine OEM Nylock Nut, 3/8-16, Grade 8, Zinc built for Genie material lifts including the Superlift Advantage, Superlift Contractor, and Super Tower, as well as the GTH-844 telehandler. As a genuine OEM part, it is manufactured to the exact grade, thread, and finish specifications Genie requires for these machines. Cross-reference part number 1257075GT against your machine's parts manual before ordering to confirm it is the correct fastener for your application.
Key Features
- Grade 8 Strength Rating — High-grade fastener construction provides the tensile strength Genie specifies for structural and load-bearing connection points on these machines.
- Zinc Finish for Corrosion Resistance — Zinc coating protects the fastener against rust and surface degradation, maintaining thread integrity in outdoor and jobsite conditions.
- Nylon-Insert Locking Thread — The nylock collar grips the mating thread to resist loosening from vibration and dynamic loads — a critical quality in mobile lifting equipment.
- Exact OEM Thread Spec — 3/8-16 thread pitch matches the original fastener exactly, allowing direct installation without rework or thread chasing.
- Broad Genie Fitment — Fits the Superlift Advantage, Superlift Contractor, Super Tower material lifts, and the GTH-844 telehandler — one part number spanning multiple Genie equipment lines.
A Nylock nut is a standard hex nut with a nylon insert bonded into the top of the nut. As the nut is threaded onto a bolt, the nylon deforms around the threads, creating friction that locks the nut in place and prevents it from backing off under vibration or repeated stress. When a Nylock nut loses its locking effectiveness — through reuse, heat exposure, or damage to the nylon insert — the fastened joint can loosen over time, compromising the structural integrity of the assembly it secures. Replacing a worn or damaged nut with the correct Grade 8, 3/8-16 zinc-plated OEM fastener restores the joint to the specification Genie designed for these machines.
