The Genie 1253478GT is a genuine OEM Hex Head Flange Screw, 3/8-16x2, 8, ZAG built for a wide range of Genie equipment including GS scissor lifts, S and SX telescopic boom lifts, Z and ZX articulating boom lifts, and GTH telehandlers. As a factory-sourced fastener, this screw matches the exact thread specification, grade, and finish of the original hardware installed at the time of manufacture. Cross-reference part number 1253478GT against your machine's parts manual to confirm it is the correct item for your application before ordering.
Key Features
- Genuine OEM Specification — Sourced directly from Genie, this screw meets the original thread grade, dimensional, and surface finish requirements — ensuring the fastener performs exactly as the machine was designed to use it.
- Exact-Fit Hardware — The 3/8-16x2 thread and flange geometry match the original mounting points directly, requiring no reworking of holes or mating surfaces.
- Broad Genie Fitment — Fits Genie GS scissor lifts, S and SX telescopic booms, Z and ZX articulating booms, GTH telehandlers, and TZ trailer-mounted booms across multiple model years.
- Flange Design Advantage — The integrated flange distributes clamping load across a wider bearing surface compared to a standard hex head, reducing the risk of fastener loosening under vibration and dynamic loading typical in aerial equipment operation.
A hex head flange screw combines the wrenching surface of a standard hex head bolt with a wide, integrated flange that acts like a built-in washer beneath the head. This design spreads clamping force over a larger area, helping to secure components firmly even where vibration or repeated movement could cause a conventional fastener to back out over time. Using the correct OEM-specification fastener — with the right thread pitch, grade, and finish — ensures the joint holds to the torque and load ratings the machine was engineered around. A fastener of the wrong grade or size can lead to joint failure, stripped threads, or component movement that affects machine function and safety.
