The Genie 1258136GT is a genuine OEM External Tooth Lock Washer, M5 designed for the GS-2669BE, GS-3369BE, and GS-4069BE bi-energy scissor lifts. Sourced directly from Genie, this washer matches the original component specification so it seats and locks exactly as intended at assembly. Cross-reference part number 1258136GT against your parts manual to confirm the correct fastener position before ordering. It is the right choice when you need a direct, like-for-like fastener replacement that preserves the integrity of the joint.
Key Features
- Genuine OEM Tooth Engagement — Produced to Genie's original specification, ensuring the serrated teeth bite into the mating surface and hardware the same way the factory component does.
- M5 Sizing for Direct Installation — Cut to M5 dimensions so this washer drops onto the fastener and into the joint without reworking surrounding hardware.
- Confirmed Fit for GS BE Scissor Lifts — Verified for the GS-2669BE, GS-3369BE, and GS-4069BE bi-energy scissor lift models.
- Vibration Resistance Where It Counts — The external tooth profile grips both the fastener head and the clamped surface, resisting loosening under the cyclic loads and vibrations typical of scissor lift operation.
- Fastener Joint Integrity — A failed or missing lock washer allows fasteners to back out over time, compromising structural and mechanical connections; replacing with the correct OEM part restores the joint to its designed clamping force.
An external tooth lock washer is a thin, serrated ring placed beneath a bolt head or nut to prevent the fastener from loosening under vibration and dynamic loads. The outward-facing teeth bite into both the fastener bearing surface and the material being clamped, creating mechanical resistance to rotation. On scissor lifts like the GS BE series, where structural fasteners are subject to repeated motion cycles and platform loading, a worn or missing lock washer can allow critical bolts to gradually back out — potentially affecting the stability and function of key assemblies. Replacing it promptly with the correct OEM part restores the clamping integrity that keeps those connections secure.
