The Genie 01.0003.0155GT Screw M6x20 UNI 5931 8.8 Zn is a genuine OEM fastener built for Genie GTH series telehandlers. Sourced directly from Genie, this screw meets the same dimensional and material standards as the hardware originally installed at the factory. It is confirmed to fit a wide range of GTH telehandler models, including the GTH-5519, GTH-4014 AU, GTH-4018 AU, GTH-1256, GTH-3512SX, GTH-4010SX, and many additional GTH variants. Always cross-reference part number 01.0003.0155GT against your machine's parts manual to confirm it is the correct fastener for your specific unit.
Key Features
- Genuine OEM Grade Hardware — Manufactured to UNI 5931 specification at strength grade 8.8 with a zinc (Zn) finish, matching the dimensional and tensile standards of the original fastener.
- Exact-Match Replacement — M6x20 thread form and length drop directly into the original mounting position with no modification to the fastener or the mating components.
- Broad GTH Telehandler Coverage — Fits a wide range of Genie GTH telehandlers across standard, AU, AF, R, SX, IIIA, and IIIB configurations, from compact models to full-size units like the GTH-5519.
- Zinc Coating for Durability — The Zn finish provides a layer of corrosion resistance suited to the demanding environments GTH telehandlers operate in, helping the fastener maintain clamping integrity over time.
- Correct Strength Grade — Grade 8.8 designates a medium-high tensile strength fastener appropriate for structural and mechanical assemblies — using the correct grade prevents under- or over-torquing that can compromise joint integrity.
A fastener such as this hex screw secures components together by clamping mating surfaces under controlled tension when torqued to specification. The UNI 5931 standard defines the head form, thread pitch, and dimensional tolerances of the screw, ensuring it engages correctly with its mating thread and seats flush under the head. Using a fastener of the wrong grade, thread form, or length risks stripping threads, insufficient clamping load, or mechanical failure at the joint — all of which can lead to component loosening in service. Replacing a worn, stripped, or corroded screw with the correct OEM-specified part restores the joint to its intended clamping performance.
