Genie 1257419GT Hex Flange Screw, M8-1.25X80, DIN6921, 10.9, ZAB

The Genie 1257419GT Hex Flange Screw, M8-1.25X80, DIN6921, 10.9, ZAB is a genuine OEM fastener built for Genie SX and S series telescopic boom lifts and ZX series articulating boom lifts, including the SX-150, SX-180, SX-135 XC, S-65 XC, and ZX-135/70. Sourced directly from Genie, this screw matches the original DIN6921 specification, grade 10.9 strength class, and ZAB finish used during factory assembly. Confirm part number 1257419GT against your machine's parts manual to ensure this is the correct fastener for your specific application before ordering.

Key Features

• Integrated Flange Head — The hex flange design distributes load across a wider bearing surface without a separate washer, matching the original assembly configuration exactly.
• Exact OEM Thread Specification — M8-1.25X80 thread pitch and length match the original Genie specification, ensuring proper engagement in threaded bores without rework or modification.
• Broad Boom Lift Fitment — Fits Genie SX super-boom telescopic lifts, S series telescopic booms, and ZX series articulating booms, including the SX-135 XC, SX-180, and ZX-135/70.

A hex flange screw combines a standard hex-drive head with an integral wide flange that acts as a built-in washer, spreading the clamping load and reducing the risk of surface damage or fastener pull-through in structural joints. The M8-1.25X80 designation specifies the thread diameter, pitch, and grip length — details that must match the original to achieve the correct torque and clamping force for the joint. Using the wrong grade or length can result in under-clamping or fastener failure, which in a boom lift application can compromise structural connections and take the machine out of service. Replacing a worn or damaged screw with the correct Genie OEM part ensures the joint performs as the original design intended.
