Key Features
- External Tooth Design — The serrated outer teeth bite into the mating surface under torque, resisting loosening from vibration and load cycling encountered on mobile boom lift platforms.
- Direct OEM Replacement — Installs in place of the original without modification, maintaining the intended clamp load and torque retention of the fastened joint.
- Broad TZ and TMZ Fitment — Confirmed for Genie TZ-34/20, TZ-50/30, TZ-50, TMZ-34/19, and TMZ-50/30 trailer-mounted articulating booms.
- Fastener Integrity — A worn or missing lock washer allows fasteners to back out over time; replacing it restores the clamping integrity of the assembly and keeps connections secure.
A lock washer is a thin hardened ring placed under a nut or bolt head to prevent the fastener from loosening due to vibration, shock loads, or thermal cycling. The external tooth variant grips both the fastener and the mating surface through its serrated teeth, creating resistance against rotational loosening. When a lock washer is missing, deformed, or flattened from repeated use, the fastener can gradually back out, compromising the structural integrity of the joint it secures.
