The Genie 1288291GT Socket Head Cap Screw M10-1.5X30 is a genuine OEM fastener designed for Genie GS scissor lifts and Z series articulating boom lifts, including the GS-3390, GS-4390, GS-5390, Z-45/25, and Z-45/25J IC Power. As a direct OEM replacement, this screw is manufactured to the same ISO 4762 standard, property class 12.9 specification, and zinc finish as the original hardware — meaning it goes in exactly where the factory screw came out. Confirm part number 1288291GT against your machine's parts manual to verify correct fitment for your specific unit before ordering.
Key Features
- ISO 4762 Class 12.9 Strength — Manufactured to property class 12.9, the highest common strength grade for metric socket head fasteners, with zinc plating for corrosion resistance in demanding jobsite environments.
- Exact OEM Thread and Dimensional Spec — M10-1.5X30 thread pitch and length match the original Genie specification precisely, so this screw seats and torques correctly without rework or modification.
- Broad Genie Fitment — Fits the GS-3390, GS-4390, and GS-5390 scissor lifts as well as the Z-45/25 and Z-45/25J IC Power articulating boom lifts, covering a wide range of Genie equipment.
- Genuine OEM Part — Supplied directly by Genie as an OEM replacement, ensuring the material grade, thread form, and finish meet the same standards as the hardware installed at the factory.
- Structural Integrity Where It Counts — A fastener at the correct grade and torque value holds structural joints securely. A corroded, stripped, or wrong-grade screw compromises joint clamping force and can lead to component movement or failure over time.
A socket head cap screw is a high-strength metric fastener tightened with an Allen key or hex driver rather than a standard wrench, allowing it to be used in tight or recessed locations where a hex head would not fit. The ISO 4762 standard governs the dimensional form of the socket head, while the 12.9 property class specifies the tensile and yield strength of the fastener — making it suitable for high-load structural applications on aerial equipment. When a screw of this type is missing, damaged, or replaced with an incorrect grade, the joint it secures loses its designed clamping force, which can allow components to shift, vibrate loose, or fail under load.
