The Genie 89787GT Hex Head Cap Screw, M8x20-8.8 is a genuine OEM fastener built for Genie S-40 and S-45 telescopic boom lifts and the Z-60/34 articulating boom lift. As an original Genie part, this screw meets the exact dimensional and grade specifications required for the application it serves, ensuring a correct, secure installation every time. Cross-reference part number 89787GT against your machine's parts manual to confirm it is the right fastener for your specific unit before ordering.
Key Features
- OEM-Grade Fastener Specification — Manufactured to Genie OEM standards, this M8x20 Class 8.8 screw delivers the tensile strength and thread tolerance the original design requires.
- Exact-Thread Direct Replacement — M8x20 thread and Class 8.8 hardness rating match the original fastener exactly, so it installs without modification or adjustment.
- Confirmed Fitment — Designed for Genie S-40, S-45 telescopic boom lifts, and the Z-60/34 articulating boom lift, keeping the right part matched to the right machine.
- Structural Integrity Where It Counts — A correctly rated fastener maintains clamping force and joint integrity under load; a worn, stripped, or incorrect screw can allow movement or failure at the connection point.
- Aerial-Lift Safety Assurance — On boom lifts operating at height, every fastener in a structural or mechanical connection plays a role in safe machine operation. Using the correct OEM-specified grade screw is essential to maintaining that integrity.
A fastener such as this hex head cap screw is used to secure components together at a joint or mounting point on the machine. The Class 8.8 designation indicates the screw's hardness and tensile strength rating, meaning it is engineered to hold a defined clamping load without stretching or shearing. When a screw of this type is missing, loose, or substituted with an incorrect grade, the joint it secures can shift, loosen, or fail under the stresses of normal machine operation — making it critical to replace any suspect fastener with the correct OEM specification part.
