The Genie 123668GT Socket Head Cap Screw, 5/16-18x2.50 is a genuine OEM fastener built for Genie GTH series telehandlers, including the GTH-636, GTH-644, GTH-842, GTH-844, GTH-1048, and GTH-1056. Sourced directly from Genie, this screw meets the exact thread pitch, head geometry, and material grade specified for these machines. Cross-reference part number 123668GT against your machine's parts manual to confirm it is the correct item for your application before ordering.
Key Features
- Genuine OEM Grade Steel — Manufactured to Genie's material and dimensional specifications, ensuring the correct hardness, thread tolerance, and head profile for a secure, lasting installation.
- Exact Thread and Size Match — 5/16-18 UNC thread with a 2.50-inch length installs directly into the designed bore without modification, delivering a flush, torque-correct fit.
- Broad GTH Telehandler Coverage — A single part number covers the GTH-636, GTH-644, GTH-842, GTH-844, GTH-1048, and GTH-1056, making it a practical stocking item for mixed GTH fleets.
- Socket Drive Advantage — The hex socket head allows precise torque application in tight or recessed locations where a standard hex head tool cannot get full engagement, reducing the risk of under- or over-torquing during reassembly.
- Structural Integrity Where It Counts — A stretched, stripped, or incorrect fastener compromises the joint it secures; replacing worn hardware with the correct OEM screw restores the clamping force the assembly was designed to rely on.
A socket head cap screw uses an internal hex (Allen) drive socket recessed within a cylindrical head, allowing it to seat flush or below a surface and be driven with high torque in confined spaces. The 5/16-18 designation identifies a coarse Unified National thread at 18 threads per inch, a common fastener specification found throughout the structural and mechanical assemblies of GTH telehandlers. When a screw of this type is damaged, corroded, or replaced during service, substituting an incorrect thread pitch or length can result in cross-threading, insufficient clamping force, or fastener failure — all of which can lead to component movement or joint separation under load.
