Confirm part number 1257865GT against your machine's parts manual to ensure it is the correct fastener for your application.
Key Features
- Exact-Thread Replacement — 3/4-16 thread specification ensures the nut seats correctly on mating hardware without reworking or shimming.
- Top Lock Flange Design — The integrated flange distributes clamping load evenly across the joint face, while the top lock feature resists loosening under vibration and cyclical loading typical on boom lifts.
- Verified Fitment — Designed for Genie S-60 J telescopic boom lifts and Z-62/40 articulating boom lifts, so you order with confidence that it matches the application.
- Structural Fastener Integrity — A loose or incorrect fastener on a boom lift can compromise joint integrity at height; using the correct OEM specification nut keeps the connection within the design parameters of the machine.
A top lock flange nut combines a built-in flange washer with a locking mechanism at the top of the nut to keep it securely in place once torqued. The flange spreads the load across a wider bearing surface than a standard nut, protecting the material around the fastener joint, while the locking feature prevents the nut from backing off under the vibration and dynamic loads that boom lift structures experience during operation and travel. When a fastener of this type becomes damaged, stripped, or corroded, it must be replaced with a part of the correct thread size, grade, and finish to restore the joint to its original specification.
