The Genie 01.4001.0078GT Hex Flange Screw M8x20 is a genuine OEM fastener built for Genie GTH telehandlers, S series telescopic boom lifts, and Z series articulating boom lifts. Manufactured to DIN 6923 standard in property class 8.8 with a zinc-plated finish, this screw delivers the dimensional accuracy and material strength Genie specifies for the application. Cross-reference part number 01.4001.0078GT against your machine's parts manual to confirm it is the correct fastener for your unit before ordering.
Key Features
- DIN 6923 Compliant, Class 8.8 Construction — Property class 8.8 steel meets the tensile and yield strength Genie specifies, so the fastener holds clamping load under the vibration and stress of regular machine operation.
- Zinc-Plated Finish for Corrosion Resistance — The ZN coating guards against rust and surface degradation, helping the screw maintain its integrity in outdoor and all-weather jobsite conditions.
- Exact OEM Dimensions — M8x20 Thread and Length — Produced to Genie OEM specifications, this screw installs directly in place of the original without modification, with correct thread engagement and flange bearing surface.
- Broad Fitment Across Genie Equipment Families — Fits a wide range of GTH telehandlers, S series telescopic booms including the S-60 FE Hybrid and S-60 DC, and Z series articulating booms including the Z-45 and Z-60 variants.
- Genuine OEM Part from Genie — Sourced directly through the Genie OEM supply chain, ensuring this part matches the original specification in material grade, thread form, and flange geometry.
A hex flange screw combines a standard hex-drive head with an integrated flange that distributes clamping load across a wider bearing area, reducing the risk of surface damage and improving joint security without a separate washer. In equipment that operates under continuous vibration — such as boom lifts and telehandlers — maintaining correct fastener specification is essential; an undersized or incorrect-grade screw can loosen, strip, or fail under load. Replacing a worn or missing fastener with the correct OEM part restores the joint to its original clamping specification and keeps the assembly secure during machine operation.
