The Genie 104393GT is a genuine OEM Lock Washer, M18, Lug designed for the Genie TZ-50 trailer-mounted articulating boom lift. Sourced directly from Genie, this washer meets the original engineering spec for the TZ-50, ensuring a correct, secure fit every time. Cross-reference part number 104393GT against your TZ-50 parts manual to confirm this is the right washer for your application before ordering.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the exact material hardness and locking-tooth profile specified for the M18 lug application on the TZ-50, so clamping force is maintained under load and vibration.
- M18 Lug-Specific Profile — The lug-style design seats flush against the mating fastener and surface, delivering the bite needed to prevent loosening during operation without damaging surrounding hardware.
- Direct-Fit for the TZ-50 — Engineered specifically for the Genie TZ-50 trailer-mounted articulating boom, eliminating guesswork when selecting a replacement washer for this machine.
- Maintains Joint Integrity — A correctly functioning lock washer keeps critical fastener assemblies torqued and secure; a worn or missing washer can allow fasteners to back out, leading to loose structural connections or component misalignment.
- Operational Safety Relevance — On trailer-mounted aerial booms, fastener security at structural and pivoting joints is directly tied to safe lift operation — using the correct OEM washer supports the integrity of those connections.
A lock washer is a thin hardened ring placed under a nut or bolt head to resist loosening caused by vibration, rotation, and dynamic loading. On a trailer-mounted boom like the TZ-50, which travels on public roads and operates at height, fasteners throughout the boom structure, axle, and stabilizer assemblies are subject to continuous movement and stress. When a lock washer wears flat, cracks, or goes missing, the fastener it secures can gradually back out, compromising joint tightness and — in load-bearing applications — structural integrity. Replacing it promptly with the correct OEM part keeps fastener assemblies holding to their specified torque.
