Key Features
- Exact OEM Thread Specification — Cut to 5/16-18 thread pitch and 2.25-inch length, this screw matches the original fastener's engagement depth and torque characteristics precisely.
- Integrated Flange Design — The flange head distributes clamping load over a wider bearing surface, eliminating the need for a separate washer and reducing the risk of joint loosening under vibration.
- Broad Genie Fitment — A single part number covers Genie S series telescopic booms, GS scissor lifts, and GTH telehandlers, making it a practical stocking item for mixed Genie fleets.
- Genuine OEM Sourcing — Sourced directly through Genie's OEM supply chain, ensuring dimensional conformity with the hardware used at initial assembly.
A hex head flange screw combines the clamping function of a standard hex bolt with an integral flange that acts as a built-in washer, spreading the load across the joint face. This reduces surface pressure on the mating material and helps the fastener resist loosening caused by machine vibration and cyclical loading. When a fastener of this type is worn, stripped, or missing, the joint it secures can shift or loosen, potentially leading to component misalignment or structural play in the assembly — so replacing it with the correct OEM specification is essential to restoring the joint's original holding strength.
