The Genie 1255642GT is a genuine OEM Hex Head Cap Screw, 5/16-18X1.75, 8, ZAG built for Genie telescopic and articulating boom lifts and GTH telehandlers. As a direct OEM replacement, this fastener meets the exact dimensional and material specifications Genie requires for these machines. It fits the S-60 XC, S-65 XC, S-60 HF, S-65 HF, Z-62/40, and GTH-1056 — cross-reference part number 1255642GT against your machine's parts manual to confirm the correct application before ordering.
Key Features
- Grade 8 Zinc-Plated Construction — The grade 8 rating and zinc-alloy plating (ZAG) deliver the clamping strength and corrosion resistance this fastener needs to perform in demanding outdoor environments.
- Exact OEM Thread Specification — Cut to a 5/16-18 thread pitch and 1.75-inch length, this screw installs directly without modification, maintaining the torque values and joint integrity Genie specifies.
- Genuine Genie Part — Sourced directly from Genie as an OEM component, ensuring full dimensional conformity and material consistency with the original hardware on your machine.
- Broad Fitment Across Key Genie Families — Compatible with S-60 XC, S-65 XC, S-60 HF, S-65 HF, Z-62/40, and GTH-1056 — covering both boom lifts and telehandler applications in the Genie lineup.
- Structural Integrity Where It Counts — A fastener at the correct grade and length holds assemblies securely under load. A wrong-grade or worn screw risks loosening or joint failure, particularly on machines working at height.
- Safety-Relevant Fastener — On aerial lifts and telehandlers, fastener integrity directly supports safe operation. Using the correct OEM-specified screw — rather than a mismatched substitute — ensures the joint performs as designed.
A hex head cap screw is a threaded fastener driven by a wrench or socket, used to clamp or secure structural and mechanical assemblies on the machine. The grade 8 designation indicates a high-strength steel alloy capable of sustaining significant clamping load, while the zinc-alloy plating resists surface corrosion during outdoor use. When a fastener is under-grade, the wrong length, or worn, it can lose clamping force or fail entirely — compromising the integrity of the assembly it secures. Replacing it with the correct OEM screw restores the joint to its designed holding capacity.
