The Genie 104450GT is a genuine OEM Internal Star Washer M16 designed for Genie TZ-50/30 and TZ-50 trailer-mounted articulating boom lifts. As a direct OEM replacement, this washer is manufactured to the same specification as the original hardware installed at the factory, ensuring a correct, consistent fit in the fastener assembly. Cross-reference part number 104450GT against your machine's parts manual to confirm application before ordering. Built to Genie's engineering requirements, this component delivers the holding integrity your fastener connection depends on.
Key Features
- OEM-Grade Tooth Engagement — Manufactured to Genie's original specification, the internal serrations grip the fastener and mating surface to resist rotation and loosening under load and vibration.
- Exact M16 Sizing — Matched to the M16 hardware used in the original assembly, this washer drops into place without modification, aligning cleanly with the bolt and bearing surface.
- Confirmed Fitment for TZ Trailer Booms — Fits Genie TZ-50/30 and TZ-50 trailer-mounted articulating boom lifts, covering both variants in the TZ-50 family.
- Maintains Joint Integrity — A worn or missing star washer allows fastener vibration-loosening over time, which can compromise structural connections; replacing with the correct part restores the designed clamping performance.
- Structural Safety Relevance — On aerial boom lifts, fastener integrity in structural and pivot connections is directly tied to safe operation; using the correct OEM washer supports the designed fastener preload and connection security.
An internal star washer uses inward-facing serrations that bite into the underside of a bolt head or nut and the surface below it, creating mechanical resistance that prevents the fastener from backing out due to vibration or cyclic loading. On trailer-mounted boom lifts like the TZ-50/30 and TZ-50, which travel over roads and uneven ground and operate under dynamic boom loads, this type of locking hardware plays an important role in keeping fastened joints secure throughout the service cycle. When an internal star washer is missing, deformed, or flattened from over-torque, the fastener loses its locking mechanism and may gradually loosen, making timely replacement with the correct OEM part an important part of routine hardware inspection.
