The Genie 104456GT is a genuine OEM Internal Star Washer,.625 designed for Genie TZ-50/30 and TZ-50 trailer-mounted articulating boom lifts. As a factory-sourced component, this washer is manufactured to the exact material and dimensional standards required for these machines. It is the correct replacement when servicing fastened joints where vibration resistance and secure clamping are critical. Cross-reference part number 104456GT against your Genie parts manual to confirm fitment before ordering.
Key Features
- Genuine OEM Material Grade — Manufactured to Genie's exact hardness and tooth-profile specifications, ensuring the internal serrations grip the mating surface and resist loosening under load and vibration.
- Direct-Fit Installation — Sized at .625 to seat correctly on the designed fastener without shimming, trimming, or adjustment, so reassembly is straightforward.
- Confirmed Fitment — Verified for Genie TZ-50/30 and TZ-50 trailer-mounted articulating boom lifts; always verify using your machine's parts manual and serial number.
- Vibration Resistance — The internal star profile bites into both the fastener head and the clamping surface, maintaining clamp load through the repeated movement and transport cycles these trailer-mounted units experience.
- Structural Joint Integrity — On aerial equipment, a washer that loses grip can allow fastener movement in structural or safety-critical connections; using the correct OEM washer helps keep each joint torqued and secure over the service life of the machine.
An internal star washer — also called an internal tooth lock washer — is a thin, hardened ring with inward-pointing serrations stamped around its inner edge. When a fastener is torqued down, those teeth bite into the underside of the bolt head or nut and into the clamping surface simultaneously, creating mechanical resistance that prevents the fastener from backing out due to vibration or cyclical loading. On trailer-mounted boom lifts like the TZ-50/30 and TZ-50, which travel over roads and rough terrain between job sites, maintaining clamp load across the machine's structural and mechanical connections is essential. A worn or missing lock washer can allow fasteners to loosen gradually, leading to joint movement, component wear, and potential safety concerns that a simple hardware replacement could have prevented.
