Key Features
- Grade 8 Strength Rating — GR8 specification delivers the high tensile strength required for structural fastening points on Genie material lift equipment.
- Zinc Finish for Corrosion Resistance — Zinc coating provides a protective barrier against rust and corrosion, extending service life in outdoor and jobsite environments.
- Nylock Locking Element — The nylon insert resists vibration-induced loosening, keeping the fastener securely in place through normal operating cycles.
- 1/2-13 Thread Specification — Exact thread pitch and diameter ensure a proper mating fit to the intended fastener point without modification.
- Genuine OEM Part — Sourced directly from Genie, this nut matches the original hardware specification for Superlift Advantage, Superlift Contractor, and Super Tower units.
A Nylock nut uses a nylon insert at the top of the nut that deforms around the bolt thread when tightened, creating friction that prevents the nut from backing off under vibration or dynamic loading. On portable material lifts like the Genie Superlift and Super Tower, fasteners at structural joints and mast connections are subject to repeated loading cycles during raising and lowering operations. A nut that has lost its locking function — or one installed at the wrong grade — can work loose over time, compromising the integrity of the joint. Replacing worn or damaged hardware with the correct OEM-specification Nylock Nut keeps fastened connections secure and maintains the structural integrity of the assembly.
