Key Features
- Genuine OEM Material Integrity — Manufactured to Genie's exact hardness and dimensional tolerances for an M3 lock washer, so the spring tension that prevents fastener loosening is consistent and dependable.
- Drop-In Replacement — This washer installs directly onto M3 fastener assemblies without modification, matching the original thread engagement and seating profile.
- Confirmed Fitment for the TMZ-34/19 — Sourced specifically for the TMZ-34/19 trailer-mounted articulating boom, so you can order with confidence that this is the correct part for that machine.
- Prevents Fastener Backing Out — The locking design bites into both the fastener and the mating surface under load, maintaining clamping force across vibration and repeated duty cycles common on trailer-mounted equipment.
- Structural Connection Integrity — On aerial equipment, loose fasteners in critical assemblies can compromise structural and mechanical function; using the correct OEM lock washer helps ensure fastener connections hold to specification.
A lock washer is a thin, hardened ring installed beneath a nut or bolt head to resist loosening caused by vibration, dynamic loads, and thermal cycling. The washer's split or toothed edge bites into the mating surfaces when tightened, creating friction that keeps the fastener from backing out during operation. When a lock washer is missing, worn flat, or substituted with an incorrect size, the fastener can gradually work loose — leading to play in mechanical joints, accelerated wear on surrounding components, or fastener loss that requires more extensive repairs to correct.
