Key Features
- Exact OEM Thread Spec — Cut to a 1/2-13 UNC thread and 1.25-inch grip length, this screw installs directly in place of the original with no chasing, recutting, or shimming.
- Broad Genie Fitment — Fits S-60 telescopic boom lift variants and the GTH-636, GTH-644, GTH-842, GTH-844, and GTH-1056 telehandlers, making it a useful stock item across a mixed Genie fleet.
- Genuine OEM Part — Sourced directly from Genie, this fastener matches every original material grade, dimensional tolerance, and finish specification — so there is no guesswork on strength or sizing.
A hex head cap screw is a fully threaded or partially threaded fastener used to clamp, secure, or locate components on a machine. When a fastener of this type stretches, strips, or corrodes, the clamped joint can loosen — leading to component movement, accelerated wear on mating parts, and potential structural failure at that location. Replacing a worn or damaged fastener with the correct OEM-specified grade and thread form restores the original clamping force and keeps the joint performing as designed.
