The Genie 1256444GT Socket Head Cap Screw, 3/8-24X.75 is a genuine OEM fastener built for Genie SX telescopic boom lifts and ZX articulating boom lifts, including the SX-150, SX-180, SX-135 XC, SX-125 XC, SX-105 XC, and ZX-135/70. Sourced directly through the Genie OEM supply chain, this screw meets the exact material grade and dimensional specifications called out in the original build. Cross-reference part number 1256444GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- A574 Alloy Steel Construction — Made to A574 specification, this grade of alloy steel delivers the tensile strength required for demanding fastener applications on large boom lifts.
- Correct Thread and Dimensional Spec — 3/8-24 fine thread with a 0.75-inch grip length; installs directly in place of the original without reworking the mating components.
- ZAG Coating for Corrosion Resistance — The zinc-aluminum-based ZAG finish provides surface protection against moisture and jobsite exposure, extending the service life of the fastener.
- Broad Fitment Across Genie's Largest Boom Lift Families — Fits SX super-boom telescopic lifts and the ZX-135/70 articulating boom, covering some of the tallest machines in the Genie lineup.
- Genuine OEM Part — Supplied as a genuine Genie OEM component, this screw conforms to the same specifications as the fastener installed at the factory, so there is no guesswork on fit or grade.
A socket head cap screw is a high-strength threaded fastener tightened with an internal hex (Allen) drive, allowing it to be installed in recessed or close-clearance locations where a standard hex head wrench cannot reach. On large boom lifts like the SX and ZX series, fasteners of this type are used in structural and mechanical assemblies where controlled clamping force and consistent torque retention matter. A fastener that is the wrong grade, thread pitch, or length can work loose under vibration or fail to develop the correct clamp load — making it important to replace like-for-like with the specified OEM part.
