The Genie 237731GT is a genuine OEM Hex Head Cap Screw, 1-8X5,5, ZAG designed for Genie S-series telescopic booms, SX-series super booms, and Z-series articulating booms. As a direct OEM replacement, this screw is manufactured to the same dimensional and material specifications as the original hardware, ensuring a consistent, repeatable installation every time. Compatible models include the SX-150, SX-180, SX-135 XC, S-40, S-45, Z-51/30J, Z-62/40, Z-45/25, Z-45/25J IC Power, Z-45 XC, Z-45/25 IC, Z-45 FE Hybrid, and Z-45 DC. Cross-reference part number 237731GT against your machine's parts manual before ordering to confirm this is the correct fastener for your unit.
Key Features
- Genuine OEM Material and Dimensional Conformity — Manufactured to Genie's original thread, grade, and zinc-alloy galvanized (ZAG) finish specifications, so the fastener performs exactly as the original did.
- Correct Thread Engagement — The 1-8 thread pitch and 5.5-inch length match the OEM torque and clamping requirements of the mounting locations on these boom lifts, eliminating the guesswork of sourcing an equivalent.
- Broad Boom-Lift Coverage — A single part number spans Genie SX super booms, S-series telescopic booms, and Z-series articulating booms, making it a practical stocking item for fleets running multiple Genie boom-lift models.
- Corrosion-Resistant Finish — The ZAG (zinc-alloy galvanized) coating resists corrosion in outdoor and variable-weather conditions, helping the fastener maintain its clamping integrity over the service life of the machine.
- Structural Fastener Integrity — A correctly torqued, properly specified fastener keeps structural and mechanical joints secure. A fastener that is worn, stripped, or incorrectly sized can allow joint movement and must be replaced with the right OEM part immediately.
A hex head cap screw is a fully threaded or partially threaded fastener driven by a wrench on its six-sided head, used to clamp or secure mechanical and structural assemblies. On Genie boom lifts, fasteners of this specification are used throughout the machine wherever high clamping force and precise torque values are required. When a fastener is damaged, corroded, or lost, replacing it with the identical OEM part — matching thread size, length, and coating — is critical to restoring the joint to its original design condition. Installing a fastener of the wrong grade or dimensions risks under- or over-clamping, which can lead to joint movement or component damage over time.
