NUT, NYLOCK, 5/16-18

The Genie 6782GT is a genuine OEM Nylock Nut, 5/16-18 designed for a broad range of Genie and Terex equipment, including GS scissor lifts, S and SX telescopic boom lifts, Z and ZX articulating boom lifts, GTH telehandlers, AL and TML light towers, and Genie material lifts and personnel lifts. As a factory-sourced component, this nut matches the exact thread specification and locking-element grade used in original assembly, making it the correct choice for any service or repair application calling for a 5/16-18 Nylock Nut. Cross-reference part number 6782GT against your Genie parts manual to confirm fitment for your specific machine serial range before ordering. With coverage spanning dozens of models across nearly every Genie product family, this is a high-utility hardware item worth keeping in any service inventory.

Key Features

• Genuine OEM Thread Integrity — Sourced directly from Genie, this nut is manufactured to the exact 5/16-18 thread pitch and nylon insert locking torque spec used in original equipment assembly.
• Vibration-Resistant Locking Element — The nylon insert grips the mating fastener and resists loosening under the constant vibration and dynamic loads that aerial lifts, telehandlers, and light towers generate in everyday use.
• Drop-In Hardware Replacement — This nut installs directly onto any 5/16-18 threaded stud or bolt without modification, fitting standard tooling used by service technicians in the field.
• Extensive Cross-Family Fitment — One part number covers GS scissor lifts, S and SX telescopic booms, Z and ZX articulating booms, TZ and TMZ trailer booms, GTH telehandlers, AL and TML light towers, Genie material lifts, and push-around personnel lifts.
• Structural Security Where It Counts — On aerial work platforms and boom lifts, fastener integrity is directly tied to structural and operational safety; using the correct OEM-spec locking nut maintains the connection torque values the machine was engineered around.

A Nylock Nut is a standard hex nut fitted with a nylon insert at the top of the nut that deforms around the mating thread when tightened, creating a friction lock that prevents the nut from backing off due to vibration or cyclic loading. On mobile equipment like scissor lifts, boom lifts, and telehandlers, fasteners are subjected to continuous vibration, travel shock, and repeated load cycles that can gradually loosen conventional nuts. The nylon insert in this nut maintains clamping force between service intervals, helping to preserve the structural integrity of the joint. When a locking nut is worn, cross-threaded, or replaced with an incorrect grade, the joint may lose preload over time, leading to component movement or fastener failure.
