The Genie 13003GT is a genuine OEM Hex Head Cap Screw, 5/8-11 x 3.5 Grd.8 built for Genie S-series telescopic boom lifts, Z-series articulating boom lifts, and GS-series rough-terrain scissor lifts. As a genuine OEM part, this screw is manufactured to the exact grade, thread pitch, and dimensional tolerances specified by Genie for these machines. Cross-reference part number 13003GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Grade 8 Strength Rating — Manufactured to Grade 8 hardness specifications, delivering the tensile strength required for structural and load-bearing fastener positions on Genie aerial equipment.
- Exact Thread and Dimensional Conformity — Cut to 5/8-11 thread spec and 3.5-inch length, matching the precise dimensions called out in the Genie parts manual — no reworking or adjustment needed at installation.
- Genuine OEM Part — Sourced directly through the Genie OEM supply chain, ensuring the material grade, finish, and geometry match the original fastener this screw replaces.
- Broad Fitment Across Genie Lift Families — Fits a wide range of Genie S-series telescopic booms, Z-series articulating booms, and GS-series rough-terrain scissor lifts, making it a practical stocking item for multi-machine fleets.
- Structural Integrity Where It Counts — A fastener at this grade and size is typically used in high-load structural joints. A worn, stripped, or incorrect-grade screw in such a position can compromise the integrity of the assembly it secures — replacing with the OEM-specified part restores the connection to its original rated condition.
A Hex Head Cap Screw is a fully threaded or partially threaded fastener driven by a wrench or socket on its hex head, used to clamp two or more components together in a bolted joint. At Grade 8, this screw carries one of the highest tensile and proof-load ratings in the inch-fastener grading system, making it appropriate for joints that must withstand significant mechanical stress, vibration, or dynamic loading — conditions common across the structural, chassis, and boom-assembly joints of aerial lifts. When a fastener in this type of joint is missing, damaged, or substituted with a lower-grade screw, the clamping force in that joint is reduced or lost entirely, which can allow components to shift, loosen, or fail under working loads. Replacing it with the correct OEM-specified part restores the joint to its intended clamping capacity.
