The Genie 1255392GT is a genuine OEM Hex Head Flange Screw, 1/2-13X4.5, 8, ZAG built for the Genie S-45 XC telescopic boom lift and TZ-34/20 trailer-mounted articulating boom. As a genuine OEM part, this fastener is manufactured to the exact thread pitch, grade, and zinc-alloy finish specified by Genie, ensuring a direct, correct-fit replacement. Confirm part number 1255392GT against your machine's parts manual before ordering to be certain this is the correct fastener for your application.
Key Features
- Exact Thread and Dimensional Fit — The 1/2-13X4.5 thread form and flange diameter match the original specification precisely, so the screw seats and torques correctly without modification.
- Correct Fitment for Genie Boom Lifts — Designed specifically for the S-45 XC telescopic boom and the TZ-34/20 trailer-mounted articulating boom, keeping replacements straightforward on both platforms.
- Integrated Flange Bearing Surface — The built-in flange distributes clamping load across a wider area than a standard hex bolt, reducing the risk of joint loosening under vibration and repeated operational cycles.
- Genuine OEM Part from Genie — Sourced directly through the Genie OEM supply chain, so the grade, plating, and thread class are exactly what the original design calls for — no guesswork on substitutions.
A hex head flange screw combines a standard hex bolt with an integrated washer-like flange beneath the head, providing a broader bearing surface that spreads clamping load and resists loosening caused by vibration. On aerial boom lifts, fasteners in structural and mechanical joints are subject to continuous movement and cyclic loading, making correct grade and thread specification critical. A fastener that is under-grade or incorrectly sized can back out or fail to maintain proper clamping force, compromising joint integrity. Replacing a worn or damaged screw with the correct OEM-specified part restores the joint to its original condition.
