The Genie 61128GT Hex Head Cap Screw, 3/4-10 x 4 Full Thread is a genuine OEM fastener built for Genie S-series telescopic boom lifts and the Z-80/60 articulating boom lift. As a direct OEM replacement, this screw is manufactured to the exact thread specification and full-thread engagement length called out in the Genie parts manual, ensuring a proper fit wherever this fastener is used on the machine. Cross-reference part number 61128GT against your unit's parts manual to confirm it is the correct item for your application before ordering.
Key Features
- OEM Thread Precision — Manufactured to the exact 3/4-10 thread form and 4-inch full-thread length specified by Genie, ensuring full thread engagement and correct torque loading at every fastening point.
- Full-Thread Design — The full-thread configuration provides maximum grip and clamping force along the entire shank, which matters for structural and mechanical connections on boom lifts.
- Direct OEM Replacement — Sourced directly from Genie as a genuine OEM part, this screw installs in place of the original without modification or adjustment.
- Broad Boom Lift Coverage — Fits a wide range of Genie S-series telescopic booms including the S-60, S-60 XC, S-60 TRAX, S-65, S-65 TRAX, S-80, S-80X, S-85, S-100, S-100HD, S-105, S-120, S-120HD, S-125, and the Z-80/60 articulating boom.
- Structural Integrity — A fastener at the correct specification keeps assembled components properly secured. A missing, stripped, or incorrect-grade screw can allow movement or misalignment in critical connections, affecting machine function and safety.
A hex head cap screw is a fully threaded or partially threaded fastener driven by a wrench or socket, used to clamp components together or secure assemblies to a structural member. The 3/4-10 designation refers to a 3/4-inch nominal diameter with 10 threads per inch — a coarse-thread specification common in heavy structural applications where high clamping load is required. On boom lifts, fasteners of this size are typically found securing major structural and mechanical assemblies where joint integrity is essential. Using a screw of the correct thread pitch, length, grade, and thread coverage — such as this genuine OEM part — ensures the joint performs as the machine was designed to. A worn, incorrect, or under-torqued fastener in a load-bearing connection should be replaced promptly with the specified OEM component.
