Genie 6091GT Nylock Nut, 1/4-20

The Genie 6091GT Nylock Nut, 1/4-20 is a genuine OEM fastener built for a wide range of Genie equipment, including GS scissor lifts, S and SX telescopic boom lifts, Z and ZX articulating boom lifts, GTH telehandlers, light towers, and personnel and material lifts. As a factory-sourced part, this nut matches the exact thread specification and locking performance Genie specifies for the 1/4-20 fastener positions across these platforms. Cross-reference part number 6091GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.

Key Features

• Genuine OEM Fastener Grade — Manufactured to Genie's material and dimensional spec, ensuring the nylon locking insert delivers the correct prevailing torque and thread engagement for 1/4-20 fastener positions.
• Direct Replacement Fit — Matches the original 1/4-20 thread form and nut profile, so this fastener seats and torques correctly without reworking the mating hardware.
• Broad Genie Equipment Coverage — Compatible with GS scissor lifts, S and SX telescopic booms, Z and ZX articulating booms, GTH telehandlers, AL and TML light towers, and Genie personnel and material lift lines.
• Vibration-Resistant Locking Design — The nylon insert grips the bolt thread under vibration and load cycles, maintaining clamp force at fastener joints that are subject to machine movement and dynamic stress.
• Keep Spares on Hand — A common 1/4-20 fastener used across a large number of Genie equipment families; having a supply available supports routine maintenance and field repairs across your fleet.

A nylock nut — also called a nylon-insert lock nut — uses an interference-fit nylon collar at the top of the nut to resist loosening under vibration and repeated loading. As the bolt passes through the nylon ring, the insert deforms slightly around the thread flanks, generating a prevailing torque that keeps the nut from backing off without the use of a secondary locking device such as a washer or thread-locking compound. When a nylock nut is stripped, cross-threaded, or the nylon insert is heat-damaged, the joint can lose clamping force, leading to loose covers, brackets, or structural connections. Replacing a worn or damaged nut with the correct OEM part restores the joint to its original specification.
