The Genie 1255806GT Hex Flange Head Screw M12-1.75X20 is a genuine OEM fastener built for a wide range of Genie telescopic and articulating boom lifts, scissor lifts, and telehandlers. Sourced directly from Genie, this screw meets the original DIN6921 standard at property class 10.9 with a ZAB finish, matching the exact specification used in production. It is a direct replacement for the original hardware, confirmed for fitment across Genie S and SX telescopic booms, Z and ZX articulating booms, GS scissor lifts, and GTH telehandlers. Always cross-reference part number 1255806GT against your machine's parts manual to confirm it is the correct fastener for your specific unit and application.
Key Features
- OEM-Grade Fastener Specification — Manufactured to DIN6921 at property class 10.9 with a ZAB protective finish, matching the original hardware specification precisely.
- Correct Thread and Dimensional Fit — M12-1.75X20 threading and flange geometry match the original mounting points exactly, allowing straightforward installation without reworking the mating hardware.
- Broad Genie Fitment — Fits Genie S and SX telescopic booms, Z and ZX articulating booms, GS scissor lifts, and GTH telehandlers across multiple model variants and configurations.
- High-Strength Clamping — The property class 10.9 rating delivers the clamping load the original design requires; substituting a lower-grade fastener in a structural or mechanical joint risks loosening, deformation, or joint failure under load.
- Integrated Flange Design — The flange bears load across a wider surface area than a standard hex bolt, distributing clamping force and reducing the risk of embedment or damage to the mating surface over time.
A hex flange head screw combines a hex drive head with an integral wide-diameter flange that functions as a built-in washer. This flange spreads the clamping load over a larger contact area, which helps protect the mating surface and maintain joint integrity through vibration and repeated load cycles — both common conditions on aerial work platforms and telehandlers in active use. A fastener that is worn, stripped, or replaced with an incorrect grade can allow joint movement or loss of preload, compromising the structural connection it secures. Using a genuine OEM screw to the correct DIN6921 standard and property class ensures the joint performs as the original design intended.
