Genie 231087GT Hex Flange Screw, M12-1.75x25, DIN6921, 10.9, ZAB

The Genie 231087GT is a genuine OEM Hex Flange Screw, M12-1.75x25, DIN6921, 10.9, ZAB built for Genie SX telescopic boom lifts, Z and ZX articulating boom lifts, and GTH telehandlers. As a direct OEM part, the part is manufactured to the same dimensional and material standards as the original hardware installed at the factory. This screw fits machines including the SX-150, SX-180, SX-135 XC, SX-125 XC, ZX-135/70, Z-62/40, Z-45 XC, and GTH-1056, making it a versatile fastener across multiple Genie equipment families. Cross-reference part number 231087GT against your machine's parts manual to confirm it is the correct item for your specific unit and serial range.

Key Features

• Correct Thread and Geometry — M12-1.75x25 thread form and integrated flange profile match the original fastener exactly, so the screw seats and clamps as designed without modification.
• Broad Genie Fitment — Fits SX super-boom telescopic lifts, Z and ZX articulating booms, and GTH telehandlers, covering a wide range of Genie equipment families with a single part number.
• Structural Integrity — A fastener torqued to the correct specification maintains critical joint clamping load. A worn, stripped, or mismatched screw can cause joint movement or component separation, so replacing with the correct grade and thread form is essential.

A hex flange screw combines the function of a standard hex head cap screw with an integral load-spreading flange beneath the head, eliminating the need for a separate washer and ensuring even clamping pressure across the mating surface. At property class 10.9, this screw is a high-strength fastener rated for demanding structural and mechanical joints. When a fastener of this type stretches, corrodes, or is replaced with an incorrect thread pitch or grade, the joint it secures may lose the clamping force it was engineered to hold, potentially allowing movement or misalignment in connected components. Using the correct OEM replacement — verified by part number 231087GT against the appropriate Genie parts manual — ensures the joint is restored to its original specification.
