The Genie 13803GT is a genuine OEM Nylock Nut, 5/16-24 built for the Z-30/20HD articulating boom lift. As a direct OEM part, it meets the exact thread pitch and dimensional specifications required for proper installation on the machine. Sourced from Genie, this nut is the correct replacement when the original fastener needs to be refreshed during service or repair.
Key Features
- Genuine OEM Specification — Manufactured to Genie's dimensional and material standards for the 5/16-24 thread form, ensuring correct engagement and holding strength on fastened joints.
- Nylon Insert Retention — The nylon locking insert resists loosening from vibration and operational movement, maintaining clamp load over the service life of the fastened connection.
- Direct Replacement Fit — Matches the original fastener's thread pitch and hex dimensions, dropping in without modification during routine service or repair.
- Confirmed Fitment — Specified for the Genie Z-30/20HD articulating boom lift; cross-reference part number 13803GT against your machine's parts manual to confirm the correct application.
- Structural Integrity — A loose or failed fastener can allow components to shift under load; replacing worn or damaged nuts with the correct OEM part keeps connections secure and the machine operating as designed.
A Nylock nut uses a nylon collar insert at the top of the nut to grip the bolt threads and resist self-loosening caused by vibration, dynamic loads, and repeated movement — conditions common on aerial boom lifts in regular use. Unlike a standard hex nut, the nylon insert creates friction that holds the nut in position without relying on a separate locking washer. When the nylon insert is damaged, deformed, or the nut has been removed and reinstalled too many times, its locking effectiveness drops and the fastener should be replaced with a fresh part.
