The Genie 1263142GT is a genuine OEM Hex Head Cap Screw, 5/8-11X4.5, 8, ZAG built for Genie S-series telescopic boom lifts, Z-series articulating boom lifts, and TZ trailer-mounted articulating booms. As a direct OEM replacement sourced from Genie, this screw meets the exact thread spec, grade, and finish called out in the original parts manual. It is confirmed compatible with a wide range of models including the S-40 XC, S-45 TRAX, Z-45/25J Bi-Energy, Z-34/22 DC, TZ-34/20, TZ-50/30, and many others across the Genie boom lift lineup. Cross-reference part number 1263142GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Genuine OEM Grade and Finish — Supplied by Genie to the exact thread class, grade 8 specification, and ZAG zinc-alloy finish called out in the original design, ensuring dimensional conformity across every critical fastening point.
- Correct Thread Engagement — The 5/8-11 coarse thread and 4.5-inch length are engineered to seat flush and torque correctly in the mating bore without shimming or adaptation.
- Broad Boom Lift Coverage — Fits a wide range of Genie S-series telescopic booms, Z-series articulating booms, and TZ trailer-mounted articulating booms, including XC, TRAX, HF, DC, Bi-Energy, IC Power, and RJ variants.
- Structural Integrity at Every Joint — A fastener of the correct grade and dimension holds structural assemblies within their designed load tolerances. A worn, stripped, or incorrect-grade screw compromises clamping force and can allow movement at joints that must remain rigid.
- Aerial Lift Safety Compliance — On aerial work platforms, fastener integrity at structural connection points is a direct safety concern. Using the correct OEM-specified grade and finish supports the machine's designed structural performance and inspection compliance.
A hex head cap screw is a structural fastener used to clamp two or more components together at a fixed, load-bearing joint. The grade designation indicates the tensile and proof-load rating of the fastener, while the ZAG finish provides corrosion resistance suited to the exposure conditions typical on mobile equipment. When a fastener of this type loosens, strips, or is replaced with an incorrect grade or length, clamping force at the joint is reduced, which can allow unwanted movement, accelerated wear on mating components, or failure of the assembly under load. Replacing a worn or damaged screw with the correct Genie OEM part restores the joint to its original specification.
