Key Features
- Exact-Match Fit — Sized specifically as a #10 ZAG lock washer to drop directly into place on the fastener stack it was designed for, without modification.
- Broad Equipment Compatibility — Fits S series telescopic booms, Z series articulating booms, GS series scissor lifts, and GTH series telehandlers across multiple model variants.
- Secure Fastening — The lock washer's design resists loosening under vibration and load cycling, helping bolted connections stay tight through the demanding work cycles these machines endure.
- Verified Part Number — Ordering by Genie part number 1256312GT ensures you receive the correct size, finish, and locking profile for your specific application.
A lock washer sits between a fastener and the surface it clamps, using its spring tension or serrated edges to resist the vibration and movement that can cause bolts and screws to back out over time. On aerial lifts and telehandlers that experience constant motion, structural flex, and load changes, a missing or damaged lock washer allows fasteners to gradually loosen — which can lead to component misalignment or failure at the connection point. Replacing a worn or missing lock washer with the correct OEM part restores the clamping integrity of the joint and keeps the assembly performing as designed.
