The Genie 1257704GT Hex Head Cap Screw M8-1.25X12 is a genuine OEM fastener built for Genie S-series telescopic booms, Z-series articulating booms, and GTH telehandlers. Manufactured to DIN 933 specification at property class 10.9 with a zinc-aluminum-based (ZAB) corrosion-resistant finish, this screw meets the exact dimensional and strength requirements of the original hardware. Sourced directly from Genie, it is the correct replacement for this position across all listed machine variants — cross-reference part number 1257704GT against your machine's parts manual to confirm it is the right item for your unit.
Key Features
- High-Strength Class 10.9 Fastener — Property class 10.9 construction delivers the clamping load and tensile strength the OEM specifies for this application, ensuring the joint performs as designed.
- DIN 933 Dimensional Conformity — Full-thread hex head cap profile machined to DIN 933 tolerances means the screw seats correctly with no need for rework or shimming at installation.
- ZAB Corrosion-Resistant Finish — Zinc-aluminum-based coating protects against corrosion in outdoor and jobsite environments, extending the service life of the fastener at its installed position.
- Wide Fleet Coverage — A single part number covers S-series telescopic booms, Z-series articulating booms (including DC, FE Hybrid, and XC variants), and GTH series telehandlers, simplifying parts inventory for mixed fleets.
- Genuine OEM Traceability — Supplied as a Genie genuine OEM part, this screw carries the manufacturer's part number 1257704GT for straightforward ordering and parts-manual verification.
A hex head cap screw is a fully threaded fastener used to clamp or secure components together at a defined torque. At property class 10.9, this screw is engineered to handle high clamping loads without stretching or yielding, which is critical wherever structural or load-bearing assemblies are joined. A fastener that is the wrong grade, wrong thread pitch, or wrong length can lose clamp force over time, leading to loosening, joint movement, or component damage. Replacing a worn or damaged screw with the correct OEM part — matched to the original thread specification of M8-1.25 and the correct length — restores the joint to its designed clamping condition and keeps the assembly secure through normal machine operation.
