Confirmed fitment includes the GS-1330m, GTH-1048, GTH-1056, TMZ-34/19, TMZ-50/30, and TMZ-17/10 — cross-reference 49406GT against your parts manual to verify the correct application before ordering.
Key Features
- Genuine OEM Fastener Integrity — Manufactured to the original torque-retention specification for M4 fastener assemblies, ensuring the washer bites and holds under the vibration loads typical of aerial and material-handling equipment.
- Direct Drop-In Replacement — Sized to M4 metric standard, this lock washer seats correctly on existing hardware without modification, maintaining proper clamp load in the original fastener stack.
- Broad Genie Fleet Compatibility — Fits the GS-1330m micro scissor lift, GTH-1048 and GTH-1056 telehandlers, and TMZ-34/19, TMZ-50/30, and TMZ-17/10 trailer-mounted articulating booms — a single part that spans multiple machine families.
- Prevents Fastener Back-Off — The locking teeth resist rotational loosening caused by equipment vibration and cyclic loading, keeping critical assemblies secure through demanding daily use.
- Structural Safety at Fastened Joints — On aerial lift and telehandler platforms, fastener loosening at structural or hydraulic connection points is a genuine safety concern; using the correct OEM-spec lock washer helps maintain joint integrity where it matters most.
A lock washer is a thin hardened ring with a split or toothed profile that sits between a nut or bolt head and the mating surface in a fastener assembly. When the fastener is tightened, the washer's edges bite into both surfaces, creating resistance against rotational loosening — particularly important on machines subject to continuous vibration, travel over rough terrain, or repeated extension and retraction cycles. When a lock washer is missing, worn flat, or substituted with an incorrect size, the fastener can gradually back off, leading to joint movement, component misalignment, or, in critical locations, a potential safety concern that may not be immediately visible during a routine inspection.
