The Genie 01.0001.0257GT Screw M8X30 UNI 5739 8.8 ZN is a genuine OEM fastener built for Genie GTH series telehandlers. Manufactured to Genie's OEM specification — including UNI 5739 threading standard, 8.8 grade tensile strength, and zinc (ZN) corrosion protection — this screw delivers the exact dimensional and mechanical conformity required for a correct installation. It fits a wide range of GTH telehandler variants, including the GTH-5519, GTH-4014 IIIA, GTH-4014 IIIB, GTH-3007, GTH-2506, GTH-1256, GTH-1544, and numerous regional and regulatory variants across the GTH lineup. Cross-reference part number 01.0001.0257GT against your machine's parts manual to confirm it is the correct fastener for your specific unit before ordering.
Key Features
- Grade 8.8 Tensile Strength — manufactured to 8.8 mechanical grade, delivering the clamping force and shear resistance required for structural and mechanical fastening applications on GTH telehandlers.
- UNI 5739 Standard Compliance — threaded to UNI 5739 specification, ensuring correct thread form and engagement for a secure, by-the-book installation without rework or modification.
- Zinc Corrosion Protection — zinc (ZN) finish guards against surface corrosion, helping the fastener maintain its integrity and torque retention in outdoor and demanding jobsite environments.
- Broad GTH Telehandler Coverage — fits an extensive range of Genie GTH telehandler variants, including IIIA, IIIB, AU, R, SX, ACF, AF, FMS, and S configurations across multiple GTH model lines.
- Genuine OEM Part — sourced directly through the Genie OEM supply chain, so the dimensions, grade markings, and finish match the original fastener specified for these machines.
A screw of this grade and thread specification is used to fasten structural or mechanical assemblies together, providing the clamping load needed to keep components securely in place under the dynamic stresses of telehandler operation. An 8.8 grade fastener is engineered to a defined yield and tensile strength, meaning it holds its clamping force without stretching or failing prematurely — something a lower-grade substitute cannot guarantee. If a fastener in this position is stripped, corroded, or under-torqued, the joint it secures can work loose, leading to component movement, accelerated wear, or a compromised assembly that requires more extensive repair. Replacing it with the correct OEM part — verified by cross-referencing 01.0001.0257GT in your GTH parts manual — keeps the joint to the specification Genie's engineers designed for.
