The Genie 1258771GT Hex Flange Screw M8-1.25X60 is a genuine OEM fastener built for Genie S-series telescopic boom lifts, Z-series articulating boom lifts, and GTH telehandlers. Manufactured to DIN6921 standard in property class 10.9 with a ZAB finish, this screw delivers the dimensional conformity and clamping strength Genie specifies for these machines. As a genuine OEM part, it matches the thread pitch, head geometry, and coating of the original hardware exactly. Cross-reference part number 1258771GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Grade 10.9 Strength Rating — High-tensile property class 10.9 construction provides the clamping force Genie specifies, resisting loosening under load and vibration.
- DIN6921 Hex Flange Head — The integrated flange distributes clamping load across a wider bearing surface, eliminating the need for a separate washer and ensuring correct seating every time.
- ZAB Corrosion-Resistant Finish — The zinc-aluminum-based coating protects the fastener against corrosion in demanding outdoor and jobsite environments, extending service life.
- Exact OEM Thread Specification — M8-1.25 thread pitch matches the original Genie specification precisely, so this screw installs directly without chasing threads or rework.
- Broad Genie Equipment Compatibility — Fits a wide range of Genie S-series telescopic booms, Z-series articulating booms, and GTH-1056 telehandlers, covering multiple variants including XC, TRAX, HF, and FE models.
A hex flange screw combines a standard hex head with an integral load-spreading flange, functioning as both fastener and washer in a single component. The high-tensile class 10.9 rating means this fastener is engineered to hold securely even under the dynamic loads and vibration that boom lifts and telehandlers generate during operation. A fastener that is the wrong grade, wrong thread pitch, or wrong head type can work loose or fail to develop full clamping force — compromising the integrity of the joint it secures. Using the correct OEM specification screw, confirmed by cross-referencing part number 1258771GT with your parts manual, keeps each fastened joint performing as Genie designed it.
