Key Features
- Genuine OEM Dimensional Conformity — Manufactured to exact thread pitch, length, and zinc-alloy galvanized (ZAG) finish specifications, ensuring consistent torque performance and corrosion resistance in demanding field conditions.
- Direct Replacement Fit — This 3/4-10 threaded hex head cap screw installs directly into the same mounting point as the original hardware, requiring no modification to adjacent components.
- Broad Genie Fitment — Fits the S-40 XC, S-45 XC, S-40 TRAX, S-45 TRAX, S-40 HF, and S-45 HF telescopic boom lifts, as well as the GTH-1056 telehandler, covering multiple equipment families from a single part number.
- Structural Fastener Integrity — A correctly spec'd fastener holds critical assemblies securely under load and vibration. An underspec or worn fastener can work loose over time, compromising the integrity of the connection it secures.
- Corrosion-Resistant Finish — The ZAG (zinc-alloy galvanized) coating provides an added layer of protection against rust and environmental wear, supporting service life in outdoor and rough-terrain applications.
A hex head cap screw is a structural fastener used to clamp and secure machine components to a fixed torque specification. The 3/4-10 thread designation identifies the bolt's diameter and thread pitch, while the ZAG finish protects the fastener shank and head from corrosion. When a fastener of this type loosens, stretches, or corrodes, the joint it secures can develop unwanted movement or fail to carry its designed load — making timely replacement with the correct OEM part the straightforward fix. Confirm part number 1257459GT against your machine's parts manual before ordering to be certain this screw is the right item for your application.
