The Genie 111389GT is a genuine OEM Hex Head Cap Screw, 1/2-13 x 1, GR 8 built for Genie S-series telescopic boom lifts including the S-40, S-45, S-80, S-80X, and S-85. Sourced directly from Genie, this fastener meets the exact grade, thread pitch, and dimensional specifications called out in the original parts manual. When you need to match the correct fastener for your machine, cross-reference part number 111389GT against your parts manual to confirm it is the right item for your application.
Key Features
- Grade 8 Strength Rating — Manufactured to GR 8 specification, delivering the high tensile strength required for structural and load-bearing fastener positions on Genie boom lifts.
- Exact Thread and Dimensional Match — 1/2-13 UNC thread and 1-inch length conform to the OEM specification, so this screw seats and torques correctly without rework or shimming.
- Genuine OEM Part — Supplied by Genie, this fastener carries the same part number, material grade, and finish as the hardware installed at the factory, giving you a like-for-like replacement.
- Broad S-Series Compatibility — Fits the S-40, S-45, S-80, S-80X, and S-85 telescopic boom lifts, covering a wide span of the Genie S-series lineup in a single part number.
- Structural Integrity at Stake — A fastener used at the wrong grade or with incorrect thread engagement can work loose or fail under load. Replacing worn or damaged hardware with the correct GR 8 screw restores the clamping force the joint was designed for.
A Hex Head Cap Screw is a fully threaded or partially threaded fastener with a hexagonal head designed to be driven with a wrench or socket. Grade 8 hardware is heat-treated to achieve a higher tensile and proof-load rating than standard fasteners, making it the correct choice for joints that carry significant mechanical load or vibration — conditions common on boom lifts during travel and operation. Using an under-grade or incorrect-length substitute in these positions risks joint loosening or fastener failure; replacing it with the specified GR 8 screw restores the joint to its engineered clamping specification.
