The Genie 823664GT Hex Head Cap Screw, M12-1.25X40MM is a genuine OEM fastener built for Genie GTH series telehandlers, including the GTH-644, GTH-842, GTH-844, GTH-1048, and GTH-1056. Sourced directly through the Genie OEM supply chain, this screw is manufactured to the exact thread pitch, grade, and dimensional specification required by these machines. Cross-reference part number 823664GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Grade 10.9 Tensile Strength — Manufactured to a Class 10.9 metric fastener rating, delivering the high-load clamping force these telehandlers demand at critical joint locations.
- Exact Thread and Dimensional Spec — M12-1.25 fine thread pitch and 40mm length match the OEM specification exactly, so the screw seats and torques correctly without modification.
- Genuine Genie OEM Part — Supplied through the Genie OEM parts program, ensuring material grade, surface treatment, and dimensional tolerances are consistent with the original hardware.
- Broad GTH Telehandler Coverage — Fits the GTH-644, GTH-842, GTH-844, GTH-1048, and GTH-1056, covering a wide range of Genie telescopic handler configurations from a single part number.
- Structural Integrity Where It Counts — A fastener torqued to the correct grade maintains joint preload over time. Substituting an incorrect grade or thread pitch risks joint loosening, component movement, or structural failure under load.
A hex head cap screw is a structural fastener used to clamp two or more components together at a specified torque. The grade marking — in this case 10.9 — defines the tensile strength and proof load the fastener can sustain before yielding, making grade selection critical wherever high clamping force or vibration resistance is required. Using a fastener of the wrong grade, thread pitch, or length can result in insufficient clamping, thread damage, or joint failure. Replacing worn or damaged hardware with the correct OEM-spec screw restores the joint to its designed holding strength and keeps the assembly performing as intended.
