The Genie 1258395GT is a genuine OEM Hex Head Flange Screw, 3/8-16x4, 8, ZAG built for Genie S and SX telescopic booms, GS scissor lifts, and TZ and Z articulating booms. As a factory-original fastener, this screw is manufactured to the exact thread pitch, head geometry, and zinc-aluminum flake (ZAG) coating specification called out in the Genie parts manual — so it seats, torques, and performs exactly as designed. Verify part number 1258395GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Correct Thread and Size — 3/8-16 thread pitch and 4-inch length match the precise callout in the Genie parts manual, ensuring correct engagement and clamping load without modification.
- Integrated Flange Design — The hex head flange distributes clamping force evenly across the joint face, reducing the risk of fastener loosening under vibration and load cycling.
- Broad Genie Fitment — Fits a wide range of Genie equipment including S and SX telescopic booms, GS scissor lifts, and TZ and Z articulating booms — cross-reference 1258395GT against your parts manual to confirm fitment for your specific unit.
- Structural Integrity — A correctly torqued, properly sized fastener maintains the structural connections it secures; a worn, stripped, or incorrect screw can allow joint movement that affects machine function and safety.
A hex head flange screw combines a standard hex drive head with an integral flanged washer that spreads clamping load over a wider surface area than a plain bolt head alone. This makes it well suited to structural and panel joints where vibration or cyclic loading might work a conventional fastener loose over time. When a fastener in this position is found damaged, stripped, or missing, replacing it with the correct OEM part restores the joint to its designed clamping specification and prevents the movement or loosening that can develop when an incorrect fastener is used in its place.
