The Genie 1255801GT Hex Head Flange Screw is a genuine OEM fastener built for Genie S series telescopic boom lifts, GS scissor lifts, and GTH telehandlers. As a direct OEM replacement, this screw is manufactured to the same grade and dimensional specification as the original, ensuring a correct, consistent installation every time. Compatible models include the S-40 XC, S-45 XC, S-40 TRAX, S-45 TRAX, S-40 HF, S-45 HF, S-60 J, S-80 J, GS-4047, and GTH models including the GTH-636, GTH-844, GTH-1044, GTH-1056, GTH-1244, GTH-1256, and GTH-1544 — cross-reference 1255801GT against your machine's parts manual to confirm fitment for your specific unit.
Key Features
- Genuine OEM Grade 8 Construction — Manufactured to Grade 8 strength with a zinc-applied finish, matching the tensile and corrosion-resistance requirements of the original fastener.
- Exact Dimensional Fit — The 5/16-18 x 2.25 thread spec and integrated flange bearing surface seat and engage exactly as the original, eliminating the need for washers or rework at installation.
- Broad Genie Equipment Coverage — A single part number covers S series telescopic boom lifts, GS-4047 scissor lifts, and a wide range of GTH telehandler models, making it a practical stocking item for mixed Genie fleets.
- Fastener Integrity Under Load — A correctly specified flange screw distributes clamping load evenly across the joint face. A stripped, incorrect, or under-grade screw can lead to joint loosening and unplanned service intervals.
- Genuine Genie Part — Sourced directly through the Genie OEM supply chain, this fastener carries the assurance of authentic specification — no guesswork on thread form, grade marking, or finish.
A hex head flange screw combines a standard hex head with an integral flange beneath it that acts as a built-in washer, spreading the clamping force over a wider area and reducing the risk of the fastener pulling through or loosening under vibration. On working aerial lifts and telehandlers that routinely operate across uneven terrain and carry dynamic loads, fastener grade and dimensional accuracy are not interchangeable — using an incorrect substitute risks joint movement and accelerated wear in the surrounding structure. Replacing a worn or damaged screw with the correct OEM part restores the joint to its original clamping specification and keeps the assembly performing as designed.
