The Genie 1256120GT is a genuine OEM Hex Head Cap Screw, 1/2-13X3.25, 8, ZAG designed for Genie GTH telehandlers and the TZ-34/20 articulating boom. As a direct factory replacement, this screw is manufactured to the same thread form, grade, and zinc-alloy galvanized finish as the original hardware, ensuring it seats and torques correctly in your machine. Cross-reference part number 1256120GT against your machine's parts manual to confirm it is the correct fastener for your specific assembly and serial range before ordering.
Key Features
- Grade 8 Construction — High-tensile Grade 8 rating delivers the clamping strength needed to hold structural and mechanical assemblies securely under load and vibration.
- Zinc-Alloy Galvanized Finish — ZAG coating provides corrosion resistance suited to the outdoor operating environments typical of telehandlers and articulating booms.
- Exact Thread Specification — 1/2-13 UNC thread form and 3.25-inch length match the OEM specification, so the screw engages correctly without rework or modification to the mating hardware.
- Genuine OEM Part — Sourced directly from Genie, this fastener meets the same dimensional and material standards as the part that left the factory, keeping your machine in its original-specification condition.
- Broad Genie Fitment — Compatible with GTH-636, GTH-844, and GTH-1056 telehandlers, as well as the TZ-34/20 articulating boom, covering a wide range of Genie equipment in a single part number.
A hex head cap screw is a structural fastener that clamps two or more components together by developing clamping force as it is torqued to specification. The grade rating governs how much tension the fastener can sustain without yielding, and the zinc-alloy galvanized coating protects the threads and shank from corrosion that would otherwise weaken the joint over time. A fastener that is incorrect in grade, length, or thread pitch will either fail to develop the required clamping load or will damage mating threads — both conditions can compromise the integrity of the assembly it secures.
