Cross-reference part number 40766GT against your machine's parts manual to confirm it is the correct fastener for your specific unit and application.
Key Features
- Genuine OEM Fastener Grade — Sourced directly from Genie, this nut meets the torque retention and material specifications required for OEM-standard service across the equipment families it supports.
- Nylon-Insert Locking Design — The nylon collar grips the mating thread and resists loosening under vibration, keeping fastened connections secure through normal machine operation and travel.
- Broad Equipment Compatibility — Fits Genie AL and TML light towers, GS scissor lifts, S and SX telescopic boom lifts, Z articulating boom lifts, and GTH telehandlers, making this a versatile fastener for mixed Genie fleets.
- Direct OEM Replacement — Matches the original thread specification, 4-40, so it installs in place of the worn or lost original with no rework needed on the mating hardware.
- Service Stock Staple — A common hardware item across multiple machine families, keeping a supply on hand supports faster turnaround on routine maintenance and field repairs.
A Nylock nut is a standard hex nut fitted with a nylon insert at one end. When threaded onto a fastener, the nylon collar deforms slightly around the thread, creating resistance that prevents the nut from backing off under vibration or repeated load cycling. This locking action means the fastened joint stays tight without the need for additional locking hardware such as split washers or thread-locking compound. When the nylon insert wears or the nut is damaged, the self-locking property is lost and the connection can loosen — replacing it with the correct OEM part restores the original retention performance of the joint.
