Key Features
- Genuine OEM Tension Retention — Sourced directly from Genie, this wavy lock washer delivers the spring tension and material hardness required to maintain bolt clamp load under vibration and load cycles on trailer-mounted boom assemblies.
- Direct-Fit M10 Hardware — Sized to the M10 thread specification, this washer drops into place on compatible fastener positions without modification, maintaining the correct stack height and bearing surface.
- Confirmed Fitment for TZ and TMZ Booms — Fits the TZ-34/20 and TMZ-34/19 trailer-mounted articulating boom lifts, keeping your parts order aligned with the correct machine variant.
- Resists Fastener Loosening Under Dynamic Load — Wavy lock washers counteract the vibration and movement inherent to towed and deployed boom equipment, helping bolted joints stay torqued through repeated use and transport cycles.
- Structural Joint Integrity — On aerial boom equipment, loose or failed fasteners in critical assemblies can compromise structural reliability. Using the correct OEM-specified lock washer helps maintain joint integrity throughout the machine's service life.
A wavy lock washer works by using its corrugated, wave-shaped profile to apply continuous spring pressure between a fastener and the mating surface. This constant tension resists the loosening effect of vibration, thermal expansion, and mechanical movement — conditions that trailer-mounted boom lifts experience both on the road and during operation. When a lock washer becomes flattened, cracked, or corroded, it loses the ability to maintain clamp load, allowing bolts to work loose over time. Replacing worn or damaged hardware with the correct OEM-specified washer restores the clamping integrity that keeps critical joints secure.
