Key Features
- Exact M12 Sizing — Sized precisely for M12 fastener applications, seating flush and applying consistent clamping load without modification.
- Broad Genie Fitment — Fits GTH-636, GTH-844, GTH-1056, GTH-1256 telehandlers, and the Z-45 XC boom lift, covering multiple Genie equipment families from a single part number.
- Secure Fastener Retention — A lock washer in good condition prevents fastener loosening under vibration and load cycles; a worn or missing one allows hardware to back out, compromising joint integrity.
A lock washer sits between a fastener and the mating surface to resist loosening caused by vibration, torque, and repeated load cycling. On heavy-duty equipment like telehandlers and boom lifts, fastener joints are subject to constant movement and stress, making the lock washer a critical part of keeping a bolted connection tight over time. A missing or degraded lock washer allows the fastener to gradually back out, which can lead to loose hardware, damaged threads, and structural joint failure if not caught early.
