The Genie 1255538GT Hex Head Cap Screw, M8-1.25x30, DIN933, 10.9, ZAB is a genuine OEM fastener built for Genie telescopic and articulating boom lifts. As a genuine OEM part, it is manufactured to the exact DIN933 standard and 10.9 property class called out in Genie's engineering specifications, ensuring the correct torque capacity and clamping force for the application. This screw fits a wide range of Genie S, SX, and Z series booms, including the SX-180, SX-150, SX-135 XC, S-85 XC, Z-80/60, and ZX-135/70, among others. Cross-reference part number 1255538GT against your machine's parts manual to confirm it is the correct fastener for your unit before ordering.
Key Features
- Correct Grade and Specification — Manufactured to DIN933 at property class 10.9 with a ZAB finish, matching the exact mechanical grade Genie specifies for these fastener positions.
- M8-1.25x30 Dimensions — The M8 thread diameter, 1.25 mm pitch, and 30 mm length are the precise dimensions required for a correct, flush installation without rework or shimming.
- Genuine OEM Part — Supplied directly in the Genie OEM parts program, so the material grade, thread form, and coating conform to the same standards as the original hardware.
- Broad Boom Lift Fitment — Compatible with Genie S, SX, and Z series boom lifts, covering telescopic and articulating models from the S-40 XC through the SX-180 and Z-80/60.
- Structural Fastener Integrity — A fastener at the correct grade maintains the clamping load that holds structural joints in position; an incorrect or under-spec screw can allow joint movement under load.
A hex head cap screw is a fully threaded or partially threaded fastener driven by a wrench or socket and used to clamp two or more components together at a defined torque. On boom lifts, structural and mechanical fasteners at the correct property class are critical — a fastener of the wrong grade or size cannot develop the clamping force the joint is designed for, which can allow movement, fretting, or loosening over time. Replacing a worn or damaged screw with the correct OEM part, part number 1255538GT, restores the joint to its original specification and keeps the assembly performing as Genie intended.
