The Genie 01.0001.1438GT Screw M5X20 UNI 5739 8.8 ZN is a genuine OEM fastener built for Genie GTH telehandlers and select Genie Z-series articulating boom lifts. Sourced directly from Genie, this screw meets the UNI 5739 standard at property class 8.8 with a zinc finish, matching the original hardware specification for the machines it serves. Compatible models include GTH-4014, GTH-4018, GTH-5519, GTH-1544, GTH-1256, and a range of IIIA, IIIB, AU, and R variants, as well as Z33/18 and Z-33 DC Power boom lifts. Verify part number 01.0001.1438GT against your machine's parts manual to confirm it is the correct fastener for your specific unit before ordering.
Key Features
- Genuine OEM Grade Hardware — Manufactured to UNI 5739 property class 8.8 with a zinc coating, delivering the thread form, tensile strength, and corrosion resistance specified for these machines.
- Exact OEM Replacement — This screw installs directly in place of the original, with no rework or resizing needed to match the factory fastener position.
- Broad GTH Telehandler Coverage — Fits an extensive range of Genie GTH telehandler configurations, including IIIA, IIIB, AU, R, and AF variants, as well as Z33/18 and Z-33 DC Power articulating booms.
- Fastener Integrity Where It Counts — A fastener at the correct property class holds clamped joints securely under load and vibration. A substituted or worn screw can allow joint movement that leads to accelerated wear of surrounding components.
A metric hex cap screw at property class 8.8 is a medium-to-high strength fastener used where a reliable, torqueable joint is required. The zinc finish resists surface corrosion in outdoor and variable-weather working conditions. When a screw in a structural or mechanical joint is damaged, stretched, or missing, the joint it secures can shift or loosen under normal operating loads, which may cause wear on mating components or allow misalignment over time. Replacing it with the correct OEM part — the same thread pitch, length, property class, and finish — restores the joint to its original holding specification. Cross-reference part number 01.0001.1438GT against your Genie parts manual before ordering to confirm applicability to your serial number and configuration.
