Genie 824134GT Hex Flange Head Screw, M12-1.75x30, DIN6921, 10.9, ZAB

The Genie 824134GT is a genuine OEM Hex Flange Head Screw, M12-1.75x30, DIN6921, Grade 10.9, ZAB finish, built for Genie SX and S telescopic boom lifts, Z and ZX articulating boom lifts, and GTH series telehandlers. As a genuine OEM fastener, this screw is produced to the exact DIN6921 standard, thread pitch, grade, and surface specification called out in Genie's engineering documentation. Cross-reference part number 824134GT against your machine's parts manual to confirm it is the correct item for your specific unit and serial number before ordering.

Key Features

• Correct Thread and Dimensional Spec — M12-1.75x30 thread form and length match the original fastener exactly, so this screw seats and torques to specification without alteration.
• Integrated Flange Bearing Surface — The hex flange head distributes clamping load across a wider area than a standard hex bolt, protecting mating surfaces and maintaining joint integrity over the service life of the machine.
• Wide Genie Equipment Coverage — Fits SX and S telescopic booms, Z and ZX articulating booms, and GTH telehandlers including the GTH-636, GTH-844, GTH-1056, GTH-1256, SX-135 XC, SX-150, SX-180, Z-80/60, and ZX-135/70.
• Genuine OEM Part — Supplied directly by Genie, ensuring the correct grade, finish, and dimensional conformity for the fastened joint — critical on structural and mechanical connections on elevated work platforms.

A hex flange head screw combines the clamping function of a standard hex bolt with an integral flange that acts as a built-in washer, spreading load and resisting loosening under vibration. The Grade 10.9 rating means the fastener is engineered for high-stress joints where a lower-grade screw could yield, loosen, or fail over time. On aerial lifts and telehandlers, fastener integrity is directly tied to the structural reliability of the machine — a worn, corroded, or incorrect-grade screw in a critical joint can allow movement or misalignment that affects safe operation. Replacing a damaged or missing fastener with the correct OEM-specified screw, torqued to the manufacturer's value, restores the joint to its designed condition.
