The Genie 6435GT is a genuine OEM Flat Head Machine Screw, 3/8-16 x 1.25, built for GR-8, GR-12, and GR-15 vertical mast lifts and the Z-30/20 articulating boom lift. As a direct Genie OEM part, this screw is manufactured to the exact thread pitch, head profile, and length required for correct installation on the machines listed. Cross-reference part number 6435GT against your machine's parts manual before ordering to confirm it is the right item for your specific unit.
Key Features
- Exact OEM Dimensions — Manufactured to the precise 3/8-16 thread specification and 1.25-inch length, ensuring the fastener seats correctly without rework or shimming.
- Flat Head Profile — The countersunk head sits flush with the mating surface, maintaining clearances and preventing interference with adjacent components.
- Genuine Genie OEM Part — Sourced directly from Genie, this screw meets the same material grade and dimensional tolerances as the hardware installed at the factory.
- Broad Model Coverage — Fits GR-8, GR-12, and GR-15 vertical mast lifts and the Z-30/20 articulating boom, covering multiple equipment families with a single part number.
- Structural Integrity — A fastener at the correct spec holds assemblies securely; an incorrect thread pitch or length can cause joint loosening or damage to threaded bores over time.
A flat head machine screw is a countersunk fastener designed to sit flush with or slightly below the surface of the material it secures. The flat, angled underside of the head bears against a matching chamfered hole, distributing clamping load evenly and eliminating protrusions that could snag or interfere with moving parts. Using a screw of the wrong thread size, head style, or length risks stripped threads, improper clamping force, and potential joint failure — making it important to replace worn or damaged hardware with the correct OEM item every time.
