The Genie 62876GT Internal Tooth Lock Washer, 1/4 is a genuine OEM fastener component designed for Genie TMZ series trailer-mounted articulating boom lifts, including the TMZ-34/19, TMZ-50/30, and TMZ-17/10. As a direct OEM part, it is manufactured to the exact material grade and dimensional tolerances specified for these machines, ensuring a flush, secure installation without adaptation. Cross-reference part number 62876GT against your parts manual to confirm fitment before ordering. Built to handle the vibration and load demands these trailer-mounted booms encounter in the field, this washer delivers the holding security that threaded fastener assemblies depend on throughout the machine.
Key Features
- OEM-Grade Tooth Engagement — Internal serrations are formed to exact depth and hardness specifications, biting firmly into mating surfaces to resist fastener back-off under vibration and dynamic loading.
- Direct Drop-In Replacement — Sized at 1/4 inch to seat correctly on existing fastener assemblies without reworking mounting hardware or surrounding components.
- Confirmed Fitment for TMZ Booms — Fits the TMZ-34/19, TMZ-50/30, and TMZ-17/10 trailer-mounted articulating boom lifts, covering the full Genie TMZ series range.
- Fastener Security Where It Counts — A worn or missing lock washer allows bolted connections to loosen progressively; replacing it restores the clamping integrity the assembly was engineered to maintain.
- Operational Safety on Aerial Equipment — On trailer-mounted boom lifts, fastener security in structural, hydraulic, and control-system connections is directly linked to safe machine operation — using the correct OEM washer keeps those connections tight and verified.
An internal tooth lock washer works by placing serrated teeth on the inner diameter of the washer, which dig into the bearing surface of the bolt head or nut as the fastener is tightened. This mechanical interference creates resistance against rotational loosening caused by vibration, shock loads, and thermal cycling — conditions that trailer-mounted boom lifts routinely experience during transport and operation. When a lock washer loses its tooth form through corrosion, flattening, or damage, the fastener joint it protects becomes vulnerable to progressive loosening, which can compromise the integrity of critical assemblies across the machine.
