The Genie 237831GT Hex Flange Head Screw M8-1.25x25 is a genuine OEM fastener built for Genie S, SX, and Z series boom lifts, including the SX-150, SX-180, S-65 XC, Z-62/40, Z-45 XC, and Z-51/30J. Sourced directly from Genie, this screw meets the DIN6921 standard at property class 8.8 with a ZAB finish, ensuring it matches the original hardware specification exactly. Cross-reference part number 237831GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- DIN6921 Standard, Class 8.8 Strength — Manufactured to the DIN6921 hex flange head standard at property class 8.8, delivering the tensile strength and dimensional conformity the original design requires.
- ZAB Corrosion-Resistant Finish — The zinc-aluminum flake coating provides corrosion resistance suited to the demanding outdoor environments these boom lifts operate in.
- Direct OEM Replacement — As a genuine Genie part, this screw installs in place of the original hardware without modification, preserving correct clamp load and joint integrity.
- Broad Boom Lift Coverage — Fits Genie SX super-boom telescopic lifts, S-series telescopic booms, and Z-series articulating booms across multiple variants, making it a practical stocking item for fleets running mixed Genie equipment.
- Fastener Integrity Supports Structural Reliability — A fastener torqued to spec at the correct grade holds assemblies securely under the dynamic loads these machines experience during operation. A missing, stripped, or under-grade screw can allow joint movement that compromises the assembly it secures.
A hex flange head screw combines a standard hex drive head with an integrated flange that distributes clamping load over a wider bearing surface, eliminating the need for a separate washer in many applications. The flange also helps resist loosening under vibration — an important characteristic on mobile equipment that travels over uneven terrain and experiences continuous operational movement. Using a fastener of the correct grade, thread pitch, and finish ensures the joint performs as the original design intended; substituting an incorrect grade or an uncoated screw risks joint failure or accelerated corrosion over time.
