The Genie 22558GT is a genuine OEM Hex Head Cap Screw, M14 x 40MM, GR 8.8, built for a broad range of Genie equipment including S-series telescopic boom lifts, Z-series articulating boom lifts, GS scissor lifts, and GTH telehandlers. Sourced directly from Genie, this screw meets the original dimensional and grade specifications required for proper assembly. Cross-reference part number 22558GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Grade 8.8 Tensile Strength — Manufactured to GR 8.8 specification, delivering the clamping force and shear resistance the original design calls for.
- Exact OEM Dimensions — M14 x 40MM sizing matches the original fastener thread pitch and grip length for a direct, tool-ready installation without modification.
- Wide Equipment Compatibility — Fits Genie S-series telescopic booms, Z-series articulating booms, GS scissor lifts, and GTH telehandlers, as well as select Genie material lifts.
- Structural Integrity at the Joint — A correctly torqued, properly graded fastener keeps structural connections secure under load; an under-spec or worn screw compromises joint integrity and can lead to loosening or failure.
- Genuine OEM Assurance — Supplied by Genie as an OEM part, ensuring the fastener meets the material grade, thread tolerance, and dimensional conformity of the original specification.
A hex head cap screw is a fully threaded or partially threaded fastener used to clamp two or more components together in a bolted joint. The grade designation — GR 8.8 in this case — defines the tensile and yield strength of the fastener, which determines how much clamping load it can safely carry. Using a fastener of the correct grade and size is critical: an under-strength or incorrectly sized screw can loosen under vibration, strip threads, or fail under load. Replacing a worn or damaged screw with the correct OEM part restores the joint to its original specification.
