The Genie 1257805GT is a genuine OEM Hex Head Cap Screw, 1/2-13X2.75, 8, ZAG built for Genie S-series telescopic boom lifts, GS scissor lifts, the Z-80/60 articulating boom, and GTH telehandlers. As a direct OEM replacement, this screw is manufactured to the same grade, thread form, and finish specifications as the original hardware installed at the factory. Cross-reference part number 1257805GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Grade 8 Zinc-Alloy Chromate Finish — The ZAG designation indicates a zinc alloy chromate coating over a Grade 8 tensile rating, delivering corrosion resistance and the clamping strength this hardware grade demands.
- Exact Thread and Dimensional Match — Cut to a 1/2-13 thread pitch and 2.75-inch length, this screw seats and torques exactly as the original, with no re-tapping or shimming needed.
- Broad Genie Fitment — Fits Genie GS scissor lifts, S-series telescopic booms, the Z-80/60 articulating boom, and GTH telehandlers — verify against your parts manual to confirm applicability to your specific unit.
- Structural Integrity You Can Depend On — A fastener at the correct grade and torque spec holds critical assemblies in alignment. An under-spec or worn screw can allow movement and accelerate wear on surrounding components.
- Genuine OEM Assurance — Supplied by Genie as a genuine OEM part, this screw meets the same material and dimensional standards as the hardware it replaces, keeping your repair to the original specification.
A hex head cap screw is a structural fastener used to clamp and secure machine assemblies — frames, guards, brackets, and mechanical subcomponents — under defined torque loads. The Grade 8 rating means the fastener is engineered for high-strength applications where clamp load and resistance to loosening under vibration are essential. A screw that has stripped threads, corroded, or been replaced with an under-grade substitute can compromise joint integrity and lead to premature wear or loosening of the assembly it holds. Using the correct OEM-specified fastener — right grade, right thread, right length — ensures the joint performs as designed throughout the service life of the machine.
